Generic callback handling

A framework for generically handling callbacks is described herein. In accordance with one aspect, multiple components or data objects are registered. The registration of a component includes providing a context name and one or more callbacks. A callback of each registered component references to the component and is registered under a context. A trigger may be invoked in response to receiving an event, where a context is provided to the trigger based on the event. A set of callbacks that are registered under the context are then triggered. The triggered callbacks reference to components registered under the context.
