Required field validations not working in JQuery Popup MVC 4

问题

I have JQuery popups and i want to put required field validations on it and for this i have set required attributes in model and have also set the validation message for them in the view but that required field validations are not working on popups. Required field validation is working fine on forms other than JQuery Popups....Please guide me that what should i do to tackle this issue...Following is my code.

Model

[Display(Name = \"Material Code\")]
[Required(ErrorMessage = \"*\")]
public string MaterialCode { get; set; }

View

<li>
    @Html.LabelFor(m => m.MaterialCode)
    @Html.TextBoxFor(m => m.MaterialCode)
    @Html.HiddenFor(m => m.MaterialCodeId)
</li>

and following is my cod eto open a JQuery popup.

$(\'#btnAddCharge\').on(\'click\', function (event) {  
        event.preventDefault();
        var actionURL = \'@Url.Action(\"Edit\", \"Charges\", new { Id = 0, @ticketId = @TicketId, UserId = UserId })\';

        $(dialogBox).dialog({
            autoOpen: false,
            resizable: false,
            title: \'Edit\',
            modal: true,
            show: \"blind\",
            width: \'auto\',
            hide: \"blind\",
            open: function (event, ui) {
                $(this).load(actionURL, function (html) {
                    $(\'form\', html).submit(function () {
                        $.ajax({
                            url: this.action,
                            type: this.method,
                            data: $(this).serialize(),
                            success: function (res) {
                                if (res.success) {
                                    $(dialogBox).dialog(\'close\');
                                }
                            }
                        });
                        return false;
                    });
                });
            }
        });

        $(dialogBox).dialog(\'open\');
    });

The validator is parsed when the page is initially loaded. When you add dynamic content you need to reparse the validator. Modify your script to include the following lines after the content is loaded

$(this).load(actionURL, function (html) {
    // Reparse the validator
    var form = $('form');
    form.data('validator', null);
    $.validator.unobtrusive.parse(form);
    $('form', html).submit(function () {
        ....

Side note: The code you have shown does not include @Html.ValidationMessageFor(m => m.MaterialCode) but I assume this is included.
