[xwiki-users] Enable wysiwyg editor for dynamically created objects

So I'm dynamically adding objects to the page via an ajax request (get the document, create a new object of the specified type, return the object in edit mode as a JSON object). What I am not able to figure out, is how to get my textareas to become wysiwyg enabled (when appropriate). I don't quite understand how the javascript that replaces the text areas is being generated, let alone if there is a way to get it generated (and returned as part of my JSON object). Any help would be greatly appreciated! Thanks, --Matthew
