Sorry, I did misunderstand. I thought your intent was to create a
custom event. As for the hooking of functions, it seems like a bad
idea, in general. Everytime you go to remove an attribute now, jQuery
has to step through some additional code which it really shouldn't.
Why not just do something like:
$('#elem').removeClass('buttonDisabled').removeAttribute('disabled');
