[1.10] How to have a block change model upon activation?

[Rug]

Hello, I am trying to make a block that functions in a similar way to a cake: meaning that when it is right clicked it will restore hunger to the player but also change it's model to represent bites being taken out of the burger.

To do this do I require a TileEntity or just a block with metadata? How do I write the change of models when it becomes activated? I can provide code if necessary.

If you want a block like the cake, try looking at the cake's code.

The unsubtle hint is that cake has more than one block state
