..... You must have missed that SpriteFont action called "Set Text" that's in the second to last bottom grouping called "Text".
Also when it comes to CocoonJS. CJS doesn't support DOM objects at this time. So using the TextObject will result in no text. This might be changing soon, heck maybe it has changed recently. But last i tried it wasn't working.
To add on to this information. Placing DOM objects over a Canvas(C2 render target) will reduce the performance of your program. While desktops have enough power to over come this. it's still in the long run poor design to use a TextObject for games. Unless your games is more GUI widget based and don't need FPS.
