But with crizmas-mvc there's no multi way data binding, or at least not from the view to the model. The controller can set some state on itself as a reaction to UI events, but only to provide feedback to the UI (for instance you may want to disable a menu when a button is clicked). The domain data is always in the model and the view is not allowed to touch it, but only to render it.
