Occurs after all groups are removed from the Grid or from specified parent group.
|e||Object||An event object which contains the event data|
This event can be handled by creating a function in your application controller $scope and applying this function as value to an attribute in Grid directive:
The events attribute has a higher priority than the clear-groups attribute. If both attributes are set, the value from events attribute is used.
If all groups are removed from the Grid, parent object within the event data is set to null.
