Cloned Select Fields do not trigger an event

Question

I am unable to find a solution for this Table that I am cloning with JQuery. I am able to clone the table and update the ID and NAME properties to avoid html conflicts. The Select drop-down only triggers an event to its JQuery when I use the first (original) copy of the table. However, the cloned version does not trigger the required event that I am using to fill-in the Description Quantity and Price fields. I am posting my Table and JQuery. Can someone please let me know what I am missing to get this to work? I tested the JQuery by creating two tables with their respective Unique IDs that I use to trigger the event, which works fine. Then, when I use JQuery to clone the Table, the Event is not triggered.

            <table>
                <tr>
                    <td style="width:20%;">

                    <td style="width:70%;"><input id="ProductDesc1" class="form-control" style="width: 100%; border-bottom-color: black!important; border-color: white;" name="ProductDesc1" type="text" value="" /></td>
                    <td><input id="quantity1" class="form-control" style="width: 50px; border-bottom-color: black!important; border-color: white; text-align: center;" name="quantity1" type="text" value="0" placeholder="1" /></td>
                    <td>
                        <input id="ProductPrice1" class="form-control cost" style="width: 95px; text-align: center; border-bottom-color: black!important; border-color: white;" name="ProductPrice1" type="text" value="" placeholder="$0.00" />
                    </td>
                    <td>
                        <div class="input-group-addon">
                            <span class="glyphicon glyphicon-eject remove"></span>
                        </div>
                    </td>
                </tr>
            </table>

The JQuery that performs the clone and updates the ID and NAME properties:

<script>
            var template = $('#sections .section:first').clone();
            var sectionsCount = 1;
            $('body').on('click', '.addsection', function () {
                sectionsCount++;
                var section = template.clone().find(':input').each(function () {
                    var newId = this.id.substring(0, this.id.length - 1) + sectionsCount;
                    var newName = this.name.substring(0, this.name.length - 1) + sectionsCount;
                    this.id = newId; 
                    this.name = newName;
                }).end()
                    .appendTo('#sections');
                return false;
            });

            //remove section
            $('#sections').on('click', '.remove', function () {
                $(this).parent().fadeOut(300, function () {
                    $(this).parent().parent().empty();
                    return false;
                });
                return false;
            });
    </script>

Finally, the JQuery that listen to the Event to fill-in the remaining fields when I select a Product.

    $(document).ready(function () {

        $('#ProductCode1').on("change", function () { alert("It Works!") });
        $('#ProductCode2').on("change", function () { alert("It Works again!") });
        $('#ProductCode3').on("change", function () { alert("It Works a third time!") });
                    }); 
    </script>

Answer 1

jQuery code inside $(document).ready() function will work only for available DOM elements when page loaded

So in order to make it work for dynamically cloned dropdowns update your jQuery binding code like this:

This:

$(document).ready(function () {
    $('#ProductCode1').on("change", function () { alert("It Works!") });
    $('#ProductCode2').on("change", function () { alert("It Works again!") });
    $('#ProductCode3').on("change", function () { alert("It Works a third time!") });
}); 

To This:

$(document).on('change', '#ProductCode1', function(){ alert("It Works!") });
$(document).on('change', '#ProductCode2', function(){ alert("It Works again!") });
$(document).on('change', '#ProductCode3', function(){ alert("It Works a third time!") });
