How to handle bindings when nesting views?

I find myself often wrapping a Label in a ContentView. I do this so often that I have created a class (let's call it PaddedLabel) that inherits from ContentView and that contains a member of type Label. So far, so good.

My question is, when the code that makes use of this new class PaddedLabel uses a binding to set the BackgroundColor, I want PaddedLabel to set the BackgroundColor of both the ContentView and the Label. How is this best implemented?
