Hi Brian -
Here is how I would change your code:
$('[EMAIL PROTECTED]').click(function(){
$('#label').unbind('change');
if ( $("[EMAIL PROTECTED]'label_checkbox']:checked").length )
$('#label').bind('change', function(){
alert('test');
});
});
By making it such that the change event is always unbound from the
select, when a checkbox changes, you're guaranteed to never have more
than one bound at a time. Hope this helps.
