Long press menu doesn't open

[cremor]

In the official YouTube app you can long press the main (confirm) button while you are on the main menu to open a popup menu. That popup menu allows things like marking videos as not interested, adding them to watch later and other things. This menu doesn't show up in the TizenTube app. A long button press behaves like a short press, so it just plays the video.
