One of the core principles of not just Cairngorm but MVC in general is
for your views to be as dumb as possible. The less they know about
models, services, etc the better. You've essentially taken the
opposite approach. Creating reusable/generic views using your approach
wouldn't really be possible.
Also, Flex is an event driven architecture and events are another core
aspect of creating loosely coupled application components. I think
your approach will result in very brittle code that will be hard to
maintain.
