Events
User actions or data updates cause the control to interact with the JavaScript code through events and handlers. During the control instantiation (or later through the appropriate methods) the developer is supposed to attach handlers (functions) to the specified events and perform the necessary steps.
The handler function receives the first argument of the sap.ui.base.Event type, with the information about the parameters dependent on the event type and about the event source, thus allowing the usage of one handler method for several controls or events. The events from the controls superclasses (objects) can be handled as well.
