Clone div with embeded divs (row-Bootstrap

I have code which works but only partially.
It is cloning main div with embedded divs (using Bootstrap row class). What I want to achieve is have "Remove author" button hidden at the start but after cloning it will become active and I will be able to remove entry. At the moment I don't know how to activate remove button.

Here is a code:

<div id="author1" class="clonedInput">
<p id="author" name="author" class="label1">Author</p>
<div class="row">
<div class="col-md-1 col-sm-6 col-xs-4">
<input id="title" name="title" type="text" placeholder="" class="input_title textboxstyle" required="">
<p id="help-block-title" name="help-block-title" for="title" class="help-block-title">Title</p>
<div class="col-md-2">
<input id="first_name" name="first_name" type="text" placeholder="" class="input_fn textboxstyle" required="">
<p id="help-block-fn" name="help-block-fn" for="fn" class="help-block-fn">First Name</p>
<div class="col-md-2">
<input id="last_name" name="last_name" type="text" placeholder="" class="input_ln textboxstyle" required="">
<p id="help-block-ln" name="help-block-ln" for="ln" class="help-block-ln">Last Name</p>
<div class="col-md-2">
<input id="email" name="email" type="email" placeholder="abc@example.com" class="input_email textboxstyle" required="">
<p id="help-block-email" name="help-block-email" for="email" class="help-block-email">Email</p>
<div class="col-md-1 col-sm-1 col-xs-2">
<input id="checkbox" name="contact" type="checkbox" value="YES">
<p id="help-block-checkbox" name="help-block-checkbox" for="checkbox" class="help-block-checkbox">Contact</p>
<div class="col-md-2 col-sm-2 col-xs-4">
<button id="btnAdd" name="btnAdd" type="button" class="btn btn-info" >Add author</button>
<div class="col-md-2 col-sm-2 col-xs-3">
<button id="btnDel" name="btnDel" type="button" class="btn btn-danger" hidden="true">Remove author</button>


$(function () {
$('#btnAdd').click(function () {
var num = $('.clonedInput').length, // Checks to see how many "duplicatable" input fields we currently have
newNum = new Number(num + 1), // The numeric ID of the new input field being added, increasing by 1 each time
newElem = $('#author' + num).clone().attr('id', 'author' + newNum).fadeIn('slow');

// create the new element via clone(), and manipulate it's ID using newNum value

/* This is where we manipulate the name/id values of the input inside the new, cloned element
Below are examples of what forms elements you can clone, but not the only ones.
There are 2 basic structures below: one for an H2, and one for form elements.
To make more, you can copy the one for form elements and simply update the classes for its label and input.
Keep in mind that the .val() method is what clears the element when it gets cloned. Radio and checkboxes need .val([]) instead of .val('').
// <p> - section
newElem.find('.label1').attr('id', 'author_' + 'ID' + newNum).attr('name', 'author_' + 'ID' + newNum).html('Author' + newNum);

// Title - select
newElem.find('.input_title').attr('id', 'title' + 'ID' + newNum).attr('name', 'title' + 'ID' + newNum).val('');

// First name - text
newElem.find('.input_fn').attr('id', 'first_name_' + 'ID' + newNum).attr('name', 'first_name_' + 'ID' + newNum).val('');

// Last name - text
newElem.find('.input_ln').attr('id', 'last_name_' + 'ID' + newNum).attr('name', 'last_name_' + 'ID' + newNum).val('');

// Email - text
newElem.find('.input_email').attr('id', 'email_address_' + 'ID' + newNum).attr('name', 'email_address_' + 'ID' + newNum).val('');

// Insert the new element after the last "duplicatable" input field
$('#author' + num).after(newElem);
$('#ID' + newNum + '_title').focus();

// Enable the "remove" button. This only shows once you have a duplicated section.
$('#btnDel').attr('disabled', false);

// Right now you can only add 4 sections, for a total of 5. Change '5' below to the max number of sections you want to allow.
if (newNum == 5)
$('#btnAdd').attr('disabled', true).prop('value', "You've reached the limit"); // value here updates the text in the 'add' button when the limit is reached

$('#btnDel').click(function () {
// Confirmation dialog box. Works on all desktop browsers and iPhone.
if (confirm("Are you sure you wish to remove this section? This cannot be undone."))
var num = $('.clonedInput').length;
// how many "duplicatable" input fields we currently have
$('#entry' + num).slideDown('slow', function () {$(this).remove();
// if only one element remains, disable the "remove" button
if (num -1 === 1)
$('#btnDel').attr('disabled', true);
// enable the "add" button
$('#btnAdd').attr('disabled', false).prop('value', "add section");});
return false; // Removes the last section you added
// Enable the "add" button
$('#btnAdd').attr('disabled', false);
// Disable the "remove" button
$('#btnDel').attr('disabled', true);

i tried something,updated fiddle

$(document).on('click','[name="btnDel"]',function() {

if (confirm("Are you sure you wish to remove this section? This cannot be undone.")) {

  var num = $('.clonedInput').index();
  var count=$('.clonedInput').length;

    if (count - 1 === 1)
        $('#btnDel').attr('disabled', true);

return false;   });

I tried attaching all the events withon handler, check it out if it works for you.good luck.
