I assume you are still using the ProductItemRenderer in the example? It
is written in ActionScript, so there is no compiler-generated data-binding
in the renderer. Because of the pay-as-you-go philosophy, the data
provider used in the example does not dispatch collection change events,
and the DataGrid and renderers aren't listening for it.
You should be able to convert ProductItemRenderer to MXML and use
data-binding, or just have the AS version listen for the appropriate event
fired from the data item.
