When using Stickit and Trackit with a select unsavedAttributes() doesn't seem to work.

When I create a select binding with Stickit, Trackit unsavedAttributes() don't seem to update. Not sure if Trackit is still supported/working or if I'm using it wrong, but a basic demo:

You need to call model.startTracking() in order to start tracking changes so you'd probably want to call this.model.startTracking() in your initialize function.

This issue should be closed though perhaps a readme update is warranted to make this a bit more clear.
