Checkbox change event not firing

Question

This is my code:

Answer 1

Try changing

$('a').click(function() {
      $('.chk').attr('checked', true);
});

To -

$('a').click(function() {
      $('.chk').attr('checked', true).trigger('change');
 });

That should force a trigger of the 'change' event.
