Add cancellation action

[arieswandari]

Is there any way to cancel action. Currently, I do cancellation by doing re-initialization and set the callback again.

What exactly would you like to cancel? The buttons work as toggles, click again to flip the state. I'm not sure what behavior you're looking for.

I mean cancelling action without clicking. E.g user doing votes up, but backend process said its not valid and need to be cancelled (automatically,without clicking the button).
