Answer 1

Try this:

var template = $('#line_1').clone();

$('#cloneButton').click(function () {
    var rowId = $('.row').length + 1;
    var klon = template.clone();   
    console.log(klon)       
    klon.attr('id', 'line_' + rowId)
        .insertAfter($('.row').last())
        .find('option')
        .each(function () {
            $(this).attr('id', $(this).attr('id').replace(/_(\d*)$/, "_"+rowId));
        })    

        $("#line_" + rowId).append("<a href='javascript:void(0);' class='remove'>delete</a>")               
});

$(document).on("click", ".remove", function() {
  $(this).closest(".row").remove();
});

You can add a remove button on the row div itself and bind the click event using event delegation.

var template = $('#line_1').clone();

$('#cloneButton').click(function() {
  var rowId = $('.row').length + 1;
  var klon = template.clone();
  klon.attr('id', 'line_' + rowId)
    .insertAfter($('.row').last())
    .find('option')
    .each(function() {
      $(this).attr('id', $(this).attr('id').replace(/_(\d*)$/, "_" + rowId));
    })
});

$(document).on("click", ".remove", function() {
  $(this).closest(".row").remove();
});

HTML:

<div class="row" id="line_1">
  <div class="form-group col-md-2">
    <label class="control-label">State</label>
    <select class="form-control">
      <option id="Select_1">Select State</option>
      <option id="Selangor_1">Selangor</option>
      <option id="KualaLumpur_1">Kuala Lumpur</option>
      <option id="Malacca_1">Malacca</option>
      <option id="Perak_1">Perak</option>
      <option id="Kedah_1">Kedah</option>
    </select>
  </div>
  <input type="button" class="remove" value="remove" />
</div>

<a id="cloneButton" class="btn btn-primary">Add State</a>
