Open Send Communication Applet in Open UI

Hi,

We are working on Siebel Open UI 8.1.1.11. We have one requirement where on click of a image, Send Communication Applet Should open. We  tried the below code we are getting the error as "Uncaught TypeError: undefined is not a function" for the highlighted line in the below code and when checked in the Watch Expression Window, Values are not getting assigned to the Properties.

Code :

$("#User").on('click', function ()

{

   var inp = theApplication().NewPropertySet();

    inp.SetProperty("SWEMethod", "ShowPopup");  // tried removing this line

    inp.SetProperty("SWETA", "Send Communication Applet");

    inp.SetProperty("SWEH", "200");      

    inp.SetProperty("SWEW", "800");  

    inp.SetProperty("SWEM", "List");

   this.ExecuteMethod( "ShowPopup", inp);
