itemedit:changed
Fires after any changes to the content or configuration of the current Item in the Item editor. For example, this could fire when the author has updated the Item reference, changes the Item layout, updates the dynamic data or adds Item tags.
You would want to be notified about this event firing, because you might want to show a custom message in your application to indicate that the Item has changed, for example.
Examples
authorApp.on('itemedit:changed', function () {
console.log('This code executes when any part of the Item has changed.');
});
