[xwiki-users] xwiki:dom:loaded event callback function never got called

Hi all, I have the following velocity code in xwiki page, I can see the fid and fname values when I retrieve entryobj from the server side, so I want to use javascript to add the fid and fname to image link node as parameters of the href url. the problem is the javascript loaded event function never got called, why? Thanks very much.
