New Revision: 1069727

URL: http://svn.apache.org/viewvc?rev=1069727&view=rev
Log:
WICKET-3436 OnChangeAjaxBehavior can render javascript before wicket-ajax.js is 
loaded

register Wicket.ChangeHandler when 'domready' event is fired.
This way the registration doesn't depend on already loaded wicket-ajax.js
