Checkbox checked state behaviour diff after upgrade to 1.9

[vitaliykhamin@…]

Hello!

I see the difference between 1.9 and 1.8.x in case of multiple clicks on first checkbox here: ​http://jsfiddle.net/zKs8S/

Sorry if dup :)

Use .prop() to get or set the dynamic, changing, visual state of a checkbox.
