Using the array methods does not cause the dataProvider events to fire, which are need to update the control. This is true for all dataProviders.
Because of this it is best to always use the dataProvider API to work with the dataProvider. (duh!) If you really want to use the underlying methods, you can re-assign the array to the dataProvider. That will cause the control to update.
