Yes, the content of the toggleButtonBar will be determined entirely by its dataProvider. If you want to change the content of the button Bar, you must change its dataprovider.
One way to do this is to add/remove the viewstack children. But this process has always seemed unnecessarily difficult, just to change the visibility/availability or a button, so I never use a viewStack as a dataProvider for anything that needs to be dynamically controlled. Instead, I use a separate dataProvider, for the control bar, which contains the index into the viewStack, and manipulate that dataProvider to control the available buttons. A click on a button uses the index in the dataProvider to set the selectedIndex of the ViewStack.
