Kendo Ui closes all open dialogs

Question

I need to open multiple kendo windows with iframe. However, when I call the close method, I find that KendoUI closes all other open windows as well (even if close it by calling the particular window instance).

I have put in two generic methods I m using on the pages.

Page 1: on click of button open page2 by calling customDialog. Page 2: on load, call customAlert("testing 123").....

on clicking ok.... it closes both the windows.

Is there a way I can prevent this behavior?

---

Not sure what is the problem.. but this seems to be happening only on click of OK button... if I click on X button or Esc.. it seems to work fine!

Thanks in advance.

//custom Dialog used to open page views inside an iframe
//pageUrl: relativeUrl as in /myPage/index
//window title: Text that needs to be displayed on top of Dialog. default is "Information"
//$statusTracker : an element on parent page that can be used to pass outcome. sets it to '' when closed using the dialog X button.
//onCloseFunc: Parameterless callback function invoked on close
//onOpenFunc: Parameterless callback function invoked on opening dialog
function customDialog(pageUrl, windowTitle, $statusTracker, onCloseFunc, onOpenFunc) {
var instanceId = new Date().getTime();

if ($statusTracker != null) {
    $statusTracker.val('');//reset associated status
    $statusTracker.data('win-id', 'dialog' + instanceId);
}

$('body').append('<div id="dialog' + instanceId + '" />');

var $window = $("#dialog"+ instanceId),
       undo = $("#undoDialog" + instanceId)
               .bind("click", function () {
                   $window.data("kendoWindow").open();
                   undo.hide();
               });


var onClose = function () {
    undo.show();
    setTimeout(function () {
        if (typeof onCloseFunc == "function") {
            onCloseFunc();
        }
    }, 500);
};

var onOpen = function () {
    $window.css('overflow', 'hidden');
    if (typeof onOpenFunc == "function") {
        setTimeout(function () { onOpenFunc(); }, 500);
    }
};

$window.kendoWindow({
    iframe: true,
    draggable: false,
    modal: true,
    resizable: false,

//shows an alert dialog
function customAlert(message, okFunction) {

var onClose = function () {

    });

    $window.find('.alert-content').html(message || '');
}
