Bindings and MVC

I have a program I wrote a few years ago in which I was a bad programmer and implemented my model and controller in the same class. Now I'm trying to extract the model from the controller and put each into its own class. I have fields in my NIB bound to properties in the controller. Should I change them to be bound to the model or keep them bound to the controller and have pass-through setters and getters from the controller to the model?

The former seems to break the model-view-controller separation, but the latter is a whole lot of what seems like redundant code.

Thanks for any insights,
