Modal "popup" and IE11

Modal "popup" and IE11

  
First let me say that this works fine on Chrome and Firefox. Unfortunately, we do still have to support some users who use Internet Explorer.
It was working on previous versions of IE, however on  Internet Explorer 11.0.9x the modal feature no longer works.

Does anyone have any experience with the modal or making it work with IE11 that may have some insight as to possibly a settings issue on IE, or the modal it's self that is preventing it from appearing?

Has anyone else encountered this issue?


Thanks,
Braxton
It looks like it may be some sort of issue with IE's java...

The modial is triggered by a javascript function:

            select: function(start, end, allDay)
            {
 
                $("+e_cal.Id+").val(xDate(dFormat(start),dFormat(end),allDay));
                $("+ln_notify.Id+").click();
                "+CallBack_Select+"
            },
 
            eventClick: function(calEvent, jsEvent, view) {
                calEvent.ignoreTimezone=false;
 
                $("+e_cal.Id+").val(sCal(calEvent));
                $("+ln_notify.Id+").click();
 
                "+CallBack_Click+"
            },


The script throws the following error:
'SilkUIFramework_wt253_block_wtMainContent_wt134_SilkUIFramework_wtNormalSchedule_block_wtContent_wt853_wtCalendar_wte_cal' is undefined

Except when I search the source code in the DOM explorer, that EXACT div exists.

Thee specific code it breaks on is:
 $(SilkUIFramework_wt253_block_wtMainContent_wt134_SilkUIFramework_wtNormalSchedule_block_wtContent_wt853_wtCalendar_wte_cal).val(xDate(dFormat(start),dFormat(end),allDay));

div code:
<span id="SilkUIFramework_wt253_block_wtMainContent_wt134_SilkUIFramework_wtNormalSchedule_block_wtContent_wt853_wtCalendar"><div align="left" style="display: none;"><input name="SilkUIFramework_wt253$block$wtMainContent$wt134$SilkUIFramework_wtNormalSchedule$block$wtContent$wt853$wtCalendar$wte_cal" tabindex="140" class="OSFillParent" id="SilkUIFramework_wt253_block_wtMainContent_wt134_SilkUIFramework_wtNormalSchedule_block_wtContent_wt853_wtCalendar_wte_cal" type="text"><span class="ValidationMessage" id="ValidationMessage_SilkUIFramework_wt253_block_wtMainContent_wt134_SilkUIFramework_wtNormalSchedule_block_wtContent_wt853_wtCalendar_wte_cal" style="display: none;"></span>
