Hi!
Im trying to do something like a check-button that displays the circle-check icon if checked.
Right now, i try to do it like this:

1.     $( "#checknotneuerdienstsms" ).button({
2.             text: false
3.     }).change(function() {
4.         $(this).button("option", {
5.             icons: { primary: this.checked ? 'ui-icon-circle-check' : null }
6.         });
7.     });

And this works, until i am clicking the button very fast. If i do that, icon wont switch, just button is toggled on / off.... why? What am i doing wrong?
