This event can be handled by creating a function in your application controller and applying it as value to an attribute in TreeView directive:

  • item-checked-changing attribute, or
  • events attribute

The events attribute has a higher priority than the item-checked-changing attribute. If both attributes are set, the value from events attribute is used.

For cancellation, simply return a false value in this event handler.
