bug with function() and $.AJAX() plugins
There seems to be a bug with $.ajax, when you put a "plug-in" function inside the function() where the plugin only gets called once. I'm not sure if it's with all the functions, or just some of them. I know it's with the accordion for sure, but not sure if anything else behaves that way, or not.
There should be a built in ajax listener for the function().
I'm assuming that no one else has ever encountered this issue, but it wasn't solved by a discussion, so now it is a bug in the core. the temporary work around for the problem is to press f5 on the page, but the long term fix would be to patch the core.
