Additionally, if you still want to use the ajax() function, the third 
argument can be ":eval", in which case, you can return some Javascript code 
to be executed when the response is returned. Alternatively, the third 
argument can be an actual Javascript function, in which case, the returned 
value will be passed to that function.
