Bootstrap datepicker not working when put on page through a javascript function

I have implemented Bootstrap datepicker in my webpage. I am using Bootstrap for CSS Styling.
Using bootstrap recommends that JQuery and Bootstrap JS should be included in the page at last. But doing so is making bootstrap datepicker malfunction.
Following is a snippet of my page through which i am able to use datepicker as well as bootstrap JS for a bootstrap Dropdown.

<head>
<script src="../js/jquery.js"></script>

Markup inside
<div id="displaymasterblock">
has been minified and used in a JS function to get triggered on a button click. Following is that JS function-

function addtest()
{
var element = '<div class="alert alert-info fade in" id="addtestheader"><span class="glyphicon glyphicon-plus"></span>&nbsp;Add New Test</div><em>&nbsp;&nbsp;&nbsp;All fields are mandatory</em><form><div class="form-inline"><div id="formelements"><label>1. Name of Test :</label><input type="text" class="form-control" id="testname" style="height:30px;" placeholder="Maximum 20 Characters">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<label>2. Scheduled on :</label><div id="datetimepicker" class="input-append date"><input type="text" style="height:30px;" placeholder="Date & Time of Test"></input><span class="add-on" style="height:30px;"><i data-time-icon="icon-time" data-date-icon="icon-calendar"></i></span></div><script type="text/javascript">$("#datetimepicker").datetimepicker({format: "dd/MM/yyyy hh:mm:ss",todayHighlight: true,pick12HourFormat: true});</script></div></div><div class="alert alert-info fade in" id="addtestheader" style="height:25px;font-size:15px;padding:2px;"><span class="glyphicon glyphicon-user"></span>&nbsp;Select Target students for test</div><div class="form-inline"><div id="formelements"><div class = "input-group"><span class = "input-group-addon" style="width:40px;">3.

document.getElementById('displaymasterblock').innerHTML = element;
}


What aabove function does is it puts all markup inside the
<div id="displaymasterblock">

Datepicker is working i.e. calendar and clock icons are showing up and functioning perfectly when it is directly included in the markup as shown above however when i am using button click to show the same markup the datepicker stops functioning.

Please help me out here. I believe there is something wrong with external resource inclusion order but not sure.
I hope i explained myself properly.

Answer

Remove the script tag completely where you are appending the dynamic html content. After the dynamic elements are added to the dom, call the datepicker function. So modify your function like below -

  function addtest() {
      var element = '<div class="alert alert-info fade in" id="addtestheader"><span class="glyphicon glyphicon-plus"></span>&nbsp;Add New Test</div><em>&nbsp;&nbsp;&nbsp;All fields are mandatory</em><form><div class="form-inline"><div id="formelements"><label>1. Name of Test :</label><input type="text" class="form-control" id="testname" style="height:30px;" placeholder="Maximum 20 Characters">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<label>2. Scheduled on :</label><div id="datetimepicker" class="input-append date"><input type="text" style="height:30px;" placeholder="Date & Time of Test"></input><span class="add-on" style="height:30px;"><i data-time-icon="icon-time" data-date-icon="icon-calendar"></i></span></div></div></div><div class="alert alert-info fade in" id="addtestheader" style="height:25px;font-size:15px;padding:2px;"><span class="glyphicon glyphicon-user"></span>&nbsp;Select Target students for test</div><div class="form-inline"><div id="formelements"><div class = "input-group"><span class = "input-group-addon" style="width:40px;">3. Programme</span><select id="programme" name="programme" class="form-control" style="width:150px;" onchange="changeinprog();"><option value="0" selected>Select One</option><option value="1">B.Tech</option><option value="2">M.Tech</option><option value="3">MCA</option><option value="4">M.Sc.</option></select><span class = "input-group-addon">4. Branch</span><select id="branch" name="branch" class="form-control" onchange="changeofbranch();"><option value="0">Select Programme</option></select></div><div class = "input-group" style="margin-top:10px;"><span class = "input-group-addon" style="width:40px;">5. Semester</span><select id="semester" name="semester" class="form-control" style="width:150px;" onchange="changeinsemester();"><option value="0">Select Programme</option></select><span class = "input-group-addon">6. Course</span><select id="course" name="course" class="form-control" style="width:270px;" ><option value="0">Problem solving and programming skills</option></select></div></div></div><center><div id="errordiv" style="width:400px;"></div><button type="button" class="btn btn-success">Save</button><button type="button" class="btn btn-default">Cancel</button></center></form>';
      document.getElementById('displaymasterblock').innerHTML = element;

      $("#datetimepicker").datetimepicker({
          format: "dd/MM/yyyy hh:mm:ss",
          todayHighlight: true,
          pick12HourFormat: true
      });

  }
