Choice dialog only shows up once when form is inside a Bootstrap modal

[Izelude]

Hi,
I have the following scenario:
I open a Bootstrap Modal which has a form inside of it, which i want to use dirtyForms on.
here the code:

$(".modal-container")
        .on("show.bs.modal",
        function (event) {
            var button = $(event.relatedTarget); // Button that triggered the modal
            var url = button.data('url') || button.attr("href");
            var modal = $(this);

            // note that this will replace the content of modal-content ever time the modal is opened
            var modalContent = modal.find(".modal-content");
            modalContent.load(url, function (response, status, xhr) {
                $.validator.unobtrusive.parse(modalContent[0]);
                $('form').validateBootstrap(true);
                modals.refreshControls();

                //RELEVANT FOR THE QUESTION:
                $('form').dirtyForms();
                $('form').find('[type="reset"],[type="submit"]').attr('disabled', 'disabled');
                $('form').on('dirty.dirtyforms clean.dirtyforms', function (ev) {
                    var $form = $(ev.target);
                    var $submitResetButtons = $form.find('[type="reset"],[type="submit"]');
                    if (ev.type === 'dirty') {
                        $submitResetButtons.removeAttr('disabled');
                    } else {
                        $submitResetButtons.attr('disabled', 'disabled');
                    }
                });
            });
        });

also at another point in code to get the events from a x button in the top of the modal and a cancel button of the modal i use the following:

$(function() {
    $(document).bind('bind.dirtyforms', function (ev, events) {
        var originalBind = events.bind;

        events.bind = function (window, document, data) {
            originalBind(window, document, data);
            $('#btn-cancel').bind('click', events.onAnchorClick);
            $('.close').bind('click', events.onAnchorClick);
        };
    });
});

i import dirtyforms locally and use the Bootstrap dialog:

<script src="~/lib/jquery.dirtyforms/jquery.dirtyforms.min.js"></script>
 <script src="~/lib/jquery.dirtyforms/plugins/jquery.dirtyforms.dialogs.bootstrap.min.js"></script>

And it works just fine... but only once.
If i choose "leave this page" and open any modal with a form again, the dirty class is still set correctly if the form is dirty and the submit button is correctly active / inactive depending on it BUT if i close the modal in any way (be it by browser command like reload or by trying to close it with the cancel button or x button) the dirtyforms confirmation does not pop up.

Any help would be greatly appreciated!

Thx
