GridView with elements that have events

[GentleHoatzin]

Hello, i have MyMonobehaviourController that references a GridView, which data source is a list of MyObject that can each fire timed events (and the ItemVisuals must be updated after those events).

I should listen those timed events for all those MyObject in the MyMonobehaviourController (and then pass the event to the proper ItemView)?
Or i should listen each MyObject's events only in the single ItemVisuals that is actually binded to it?
