The like/dislike action works, but the change is not currently propagated to the item in the list. If you back out of the list and reload it, you should see the incremented counter. Also, if you have previously 'liked' a video, and attempt to 'like' it again, the API does not return an error, so cuteTube will respond accordingly by confirming the 'like' and incrementing the counter. However, the additional 'like' will not permanently be added by the API, so if you view the video some time later, the 'like' counter will have return to it's previous value.
