    - #### addChangeHandler

          com.google.gwt.event.shared.HandlerRegistration addChangeHandler(ChangeHandler handler)

      If this field is editable, any `change` handler specified on the ListGridField will be passed onto the editors for this field.

      Note that if `canToggle` is true, the user may change the value of a boolean field without going into edit mode by single clicking on the field. In this case the `ListGridField.change` and `ListGridField.changed` handlers will fire but the `form` and `item` parameters will be null.

      Parameters:
        `handler` - the change handler
      Returns:
        `HandlerRegistration` used to remove this handler
