Tic tac toe in sapui5 with dynamic binding of table cells

Hi,

I would like to get better in sapui5 and for that I need to work my JavaScript. For this I would like to create the tic tac toe game, with rules in JavaScript. The problem is I never develop a tic tac toe game, and I can't imagine how to do my model in JSON. And without JSON model, my dynamic binding of table cells can't appears. An idea on what I put in my JSON model for that my table appears with other thing that "no data" message?

Thank sin advance, best regards.

Ewen.
