CRM Portals OnChange Event For DateTime

Occasionally when working with CRM Portals you may run into the need to get the OnChange event for a date time field.  Because of the way that CRM Portals renders date time fields this is slightly more complicated then working with text boxes, check boxes and pick lists.  During my process I ended up reaching out to Microsoft for help on this and below are the steps they provided to help me with this problem:

1) Click on the date time control
2) Press F12
3) In console type $('div.control') and hit enter (this will give you a list of div controls)
4) Locate the div control for the date time field
5) Go to the entity form or web page in CRM and add the following code snippet (replace the 2 with the number your div control is located at):

1:      $(document).ready(function ()  
2:      {  
3:        var dpcontrol = $('div.control')[2];  
4:        $(dpcontrol).on("dp.change", function (e)   
5:        {  
6:           alert("On change Event Triggered");  
7:           alert(e.date);  
8:        });  
9:      });  

Change the 2 alerts to whatever you need to happen during the OnChange event.
