i can't catch the escape event in there there is no input field in the dialog.
in the sample bellow it's working only if there is input, when i remove it, it stop working.

 <div id="dialog-confirm2">
        Dialog
        <input type="text" /> <%--this is the redundent input i don't need in the dialog--%>
    </div>

 (function () {
                        var dialog = $("#dialog-confirm2")
                            .dialog({
 
                                resizable: false,
                                height: 150,
                                modal: true,
                                closeOnEscape: false, //hide x button
                            })
                            .on('keydown', function (evt) {
                                if (evt.keyCode === $.ui.keyCode.ESCAPE) {
                                    alert('test');
<%--more actions to do here--%>
                                     dialog.dialog('close');
                                }
                                evt.stopPropagation();
                            });
                    }());
