Move the controls to a new layer, perhaps call it "HUD", make sure to uncheck "scrollable" on that layer, this will make the layer not move and move along with the camera. Keep in mind that the position of the buttons is in the correct positions as well, if your scene is larger than 480x320, be sure to move the controls to the absolute bottom left area, this is where it will display that layer in game.
