I am trying to add block UI or similar window to indicate on going processing with in an Accordion. It's not showing up with Accordion. E.g. on list box (the control is on Accordion) change event, I want to display "Please wait" window.  My window never shows up.

Here is my code
  var myApp;
           myApp = myApp || (function () {
               var pleaseWaitDiv = $('<div class="modal hide" id="pleaseWaitDialog" data-backdrop="static" data-keyboard="false"><div class="modal-header" style="z-index: -1"><h1>Processing...</h1></div><div class="modal-body"><div class="progress progress-striped active"><div class="bar" style="width: 100%;"></div></div></div></div>');
               return {
                   showPleaseWait: function () {
                   hidePleaseWait: function () {


 $('#lstCustomView').change(function ()
           if ($('#lstCustomView').val() != "-1") {

                    $('#txtViewName').val($('#lstCustomView option:selected').html());
                    $("#btnEditView").text('Save View');
                    bootbox.alert("View Loaded.", function () {

                    //$("#btnDeleteView").attr('disabled', 'disabled');
                    //$("#btnEditView").text('Edit View');


Please advise. If you have any other sample, please let me know.

You guys are very helpful.

Thanks a lot.

We were able to re-produce the issue with triggering Listbox change event at our end. This is already a known issue and the fix will be included in our main release Volume 3, 2016.

Hi Arun,  
We are unable to reproduce the issue with triggering Change event for Listbox in Volume 3. Kindly ensure whether you have updated assembly files, script and CSS to latest Volume 3. We have upgraded the sample to Volume 3 and it can be downloaded from the following link,  

If the issue still persists at your end, please modify the sample to reproduce issue at our end. So that we can provide you a solution.
