Custom remote.xml to toggle view modes does not work [SOLVED]

I’d like to map a key on my remote to toggle the available view modes when playing a video. From list_of_built-in_function, the Container.NextViewMode directive should do it so I added it to the fullscreenvideo section of remote.xml but nothing happens when I push the button. Note – The button works with other things. As a control I mapped it to ‘Stop’ and it does stop a playing video. Is my syntax correct?

Code:
remote.xml
...
  <FullscreenVideo>
    <remote>
      <display>Container.NextViewMode</display>
    </remote>
  </FullscreenVideo>
...
