draw method does not fire "change" event

When a user uses their mouse to create a signature, the change event fires and the IsEmpty() method returns false - as expected.

However, when a signature is set using the draw() method, the change event does not fire but IsEmpty() method correctly returns false.

I believe this is a bug - the draw() method should result in the same flow as a manual/mouse signature and fire the change event.
