For
the client-side JavaScript composite controls, do they raise custom
events anywhere client-side, such that I can register for events from
multiple event handlers? Specifically, for the RichTextEditor, it's
initialized in javascript against a TextArea that is then hidden... in jquery, I might
register
$("#MyTextareaId").on("es2.richtextbox.change", function() { ...});
where es2.richtextbox.change are custom events bubbled from the framework - is this functionality present and how do I formulate the custom event names so I can respond to them?
