Javascript Question

Unable to set the value of input field onclick

I have created this custom dropdown which has custom radio buttons.
I get the value of the selected radio button and set it to span tag successfully.

What i am not getting is : i want to set the same value in the input field that is present in the dropdown, but the value is not getting set.

i use pure js as well as jquery to do so but the value is alerting and not setting into the input field.

code is live here: http://thekabir.in/onsitego-planlisting2017/index.html

Steps: click on check brands dropdown and select any brand..

jquery and js used are

//filters dropdown
function DropDown(el) {
this.dd = el;
this.placeholder = this.dd.children('span');
this.opts = this.dd.find('div.dropdown li');
this.val = '';
this.index = -1;
this.initEvents();
}
DropDown.prototype = {
initEvents : function() {
var obj = this;
obj.dd.on('click',function(){
$(this).toggleClass("active");
$(this).parent().toggleClass("border-active");
$('.filters').toggleClass('border-bottom');
$(this).children('.dropdown').css('width',$(window).width());
var deID = $(this);

if(deID[0].id == 'devicebrand')
{
$('#devicebrand i.icon-down-arrow-1').addClass('icon-up-arrow-1').removeClass('icon-down-arrow-1');
}
return false;
});
obj.opts.on('click',function(e){
// e.preventDefault();
$(this).parent().addClass('hidden');
$(this).addClass('active');
var opt = $(this);
obj.val = opt.text();
obj.index = opt.index();
obj.placeholder.text(obj.val);
var currentID = $(this).parents('div.wrapper-dropdown-3')[0].id;

if(currentID == 'devicebrand')
{
$('#devicebrand.wrapper-dropdown-3 .dropdown li').removeClass('active');
$('#devicebrand.wrapper-dropdown-3 .dropdown li span').removeClass('icon-selected-radio-yellow').addClass('icon-oval-3-copy-3');
$('#devicebrand i.icon-up-arrow-1').addClass('icon-tick-filled').removeClass('icon-up-arrow-1');
$('.more-brands').addClass('hidden');
$('.covered').removeClass('hidden');
$('#manual-brand-input').val(obj.val);
}
$(this).children('span').removeClass('icon-oval-3-copy-3').addClass('icon-selected-radio-yellow');
$(this).parent().toggleClass("border-active");
$('.dropdown input').val('');
e.stopPropagation();
});
},
getValue : function() {
return this.val;
},
getIndex : function() {
return this.index;
}
};
$(function() {
var dd = new DropDown( $('#devicebrand') );
$(document).click(function() {
// all dropdowns
$('.wrapper-dropdown-3').removeClass('active');
});
});

Main change is here: $('.dropdown input').val($(this).find('a').data('val'));

//filters dropdown
  function DropDown(el) {
      this.dd = el;
      this.placeholder = this.dd.children('span');
      this.opts = this.dd.find('div.dropdown li');
      this.val = '';
      this.index = -1;
      this.initEvents();
  }
  DropDown.prototype = {
      initEvents : function() {
          var obj = this;
          obj.dd.on('click',function(){
            $(this).toggleClass("active");
            $(this).parent().toggleClass("border-active");
            $('.filters').toggleClass('border-bottom');
            $(this).children('.dropdown').css('width',$(window).width());
            var deID = $(this);

            if(deID[0].id == 'devicebrand')
            {
              $('#devicebrand i.icon-down-arrow-1').addClass('icon-up-arrow-1').removeClass('icon-down-arrow-1');
            }
            return false;
          });
          obj.opts.on('click',function(e){
              // e.preventDefault();
              $(this).parent().addClass('hidden');
              $(this).addClass('active');
              var opt = $(this);
              obj.val = opt.text();
              obj.index = opt.index();
              obj.placeholder.text(obj.val);
              var currentID = $(this).parents('div.wrapper-dropdown-3')[0].id;

              if(currentID == 'devicebrand')
              {
                $('#devicebrand.wrapper-dropdown-3 .dropdown li').removeClass('active');
                $('#devicebrand.wrapper-dropdown-3 .dropdown li span').removeClass('icon-selected-radio-yellow').addClass('icon-oval-3-copy-3');
                $('#devicebrand i.icon-up-arrow-1').addClass('icon-tick-filled').removeClass('icon-up-arrow-1');
                $('.more-brands').addClass('hidden');
                $('.covered').removeClass('hidden');
              }
              $(this).children('span').removeClass('icon-oval-3-copy-3').addClass('icon-selected-radio-yellow');
              $(this).parent().toggleClass("border-active");
              console.log($(this).data('val'));
              $('.dropdown input').val($(this).find('a').data('val'));
              e.stopPropagation();
          });
      },
      getValue : function() {
          return this.val;
      },
      getIndex : function() {
          return this.index;
      }
  };
  $(function() {
      var dd = new DropDown( $('#devicebrand') );
      $(document).click(function() {
          // all dropdowns
          $('.wrapper-dropdown-3').removeClass('active');
      });
  });
