A handy way of debugging these issues is to examine the "length" of things that come back from your query lookups

alert ($('ContactName').length);
$('ContactName').addClass('form-control has-ns');

A length of 0 means jquery can't find the component you're looking for so is applying the class to nothing. As others have said, your selector wasn't a valid one for finding your box, $('ContactName') finds a tag called contactname, so

<ContactName/>>

Solution 1

use Attribute Equals Selector [^] for Selecting controls with Name instead of Id

JavaScript

$("input[name='ContactName']").addClass('form-control has-ns');

Here is my piece of HTML for your reference written in an aspx page which works as expected by you:-

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <style type="text/css">
        .form-control{
            border-color:red;
            border-width:2px;
            height:50px;
            width:200px;
        }
        .has-ns{
            background-color:green;
        }
    </style>
    <script src="Scripts/jquery-1.10.2.js"></script>
    <script type="text/javascript">
        $(function () {
            $("#btnAdd").bind("click", function () {
                var div = "<div>" + GetDynamicTextBox("SmrutiRanjan", "smruti.sahoo@gmail.com") + "</div>";
                $("#TextBoxContainer").append(div);
                $('input[name=ContactName]').addClass('form-control has-ns');
                return false;
            });

            $("body").on("click", ".remove", function () {
                $(this).closest("div").remove();

            });
        });        

        function GetDynamicTextBox(valuename, valueemail) {
            return '<input name="ContactName" type="text" value="' + valuename + '" /> ' + '<input name="ContactEmail" type="text" value="' + valueemail + '" /> ' +
            '<input type="button" value="Remove" class="remove" />';
        }

    </script>
</head>
<body>
    <form id="form1" runat="server">
      <div id="TextBoxContainer"></div>
      <input type="button" id="btnAdd" value="Add" />
    </form>
</body>
</html>

Hope this will definitely of help to you.
