How to cancel onBack

Hello,

Not sure if this is a bug and I haven't checked yet for other view types.

For ProgressBar, I pass a delegate that returns true on the onBack function, but when I press the back button, the view is poped from the stack.

I used the code provided on the docs: https://developer.garmin.com/connect-iq/

What am I missing?

PS: I tried on both simulator and real device.

Thank you!
