I made some research about this problem this year.

As I understand the framework, it's impossible to have a nested grid in grid component. Using some hacks, you can only create a read-only subgrid inside rowExpander plugin. (actually, you can create components inside, but you won't catch any events from them)

In your case you can try to use grouping feature to group records in your store.

I've also seen another implementation — show window with a subgrid after click on main grid row.

Hope this information will help you.
