How to associate a store or model with a carousel

I have a panel that contains a toolbar at the top and a carousel below it. I can find no option in Architect to allow me to assign a store or a model to the carousel. In my original Sencha Touch test I was able to set a store with

store: 'photoStore' but that config property does not seem to exist in Architect's config inspector.



I'm new to all this, can anyone please tell me what I'm missing?
