How to bind a click event to a radio button?

How to bind a click event to a radio button?

I am trying to bind a click event on a radio button.  The click event is not working but mouseup and mousedown is working.  Mousedown and mouseup work on a desktop browser but doesn't work on the iPad.  I am binding the event with the following selector right now on a radio button list: $('#list .ui-radio').live('mousedown', ...);

What should I use in this case?

Thanks,
