                Custom widgets in Ensemble, just like widgets in any UI framework, can dispatch events
                
                `dispatchEvent` action is used in custom widgets to let the caller of the widget know when something interesting has happened. 
                
                For example 
                - a calendar widget may dispatch an event named 'onDataRangeSelected' to notify the caller that the user selected a range of dates. 
                - in this example, we have a custom widget named `DispatchEventSample` that is a simple Form widget with two fields and a Submit button. When you tap the Submit button, `DispatchEventSample` dispatches an event namd `onFormSubmit`. A Text widget below the form just prints out the data received in the event

                      eventData.text = 'Received Data from onFormSubmit: '+event.data.name + ' ' + event.data.email
