DatePicker in dialog causes Out of stack error.

I have a datepicker on a dialog. To reproduce the problem.

1) Open Dialog

2) select a date

3) Press Cancel on dialog to close it.

4) reopen dialog.

5) Try to select a date.

The code reports an Out of Stack Error on this code

d.datepicker._updateDatepicker(b)

The date picker is a plane input control with thsi code on the dialog cshtml document

            $("#SessionDate").datepicker({
                dateFormat: 'dd/mm/yy'
            });

The Dialog is defined like this on the main cshtml document

        $(function () {

            $('a.asessionCreate').live("click", function (event) { editDialog(this, event, '#DivForCallback', '#IdGivenToPostBackFormOnDialog); });

        });   /* end document.ready() */


function editDialog(tag, event, target, formId) {
    event.preventDefault();
    var $url = $(tag).attr('href');
    var $title = $(tag).attr('title');
    var $dialog = $('<div></div>');
    $dialog.empty();
    $dialog
            .load($url)
		    .dialog({
		        autoOpen: false
			    , title: $title
			    , width: 500
                , modal: true
			    , minHeight: 200
                , show: 'fade'
                , hide: 'fade'
		    });

    $dialog.dialog("option", "buttons", {
        "Cancel": function () {
            $(this).dialog("close");
            $(this).empty();
        }
    });
};
