A new type of .live() event

A new type of .live() event

Hello.
I want propose a new "event" to .live().

See this case:
I'm using AJAX to load HTML, and for all .roundedBox I need apply in ajax.success:
  1. $('.roundedBox').css({borderRadius: 5});

I suggest any more intelligent:
  1. $('.roundedBox').live('all', function(){
  2.   $(this).css({borderRadius: 5});
  3. });
  4. // Obs: the event "all" is only a bad-suggestion, is only for example

Or be: to ALL new .roundedBox (indepentends if it is from AJAX HTML content or not), will be applied this event-method.

Currently is possible do this in an easy form?
I really don't know. If yes, how? If not, it maybe can be a good idea.

Bye.
