onChange not called by autoplay plugin

[rugheid]

Describe the bug When the slide changes because of autoplay, the onChange handler is not called. This way you can't correctly control the component while using autoplay.

To Reproduce Steps to reproduce the behavior:

1. Use controlled carousel with autoplay plugin enabled.
2. Put a console.log statement in the onChange handler.
3. Notice that it doesn't fire when autoplay advances.

Expected behavior I would expect the onChange handler to be called when the carousel changes slide because of autoplay.
