Need list view to update after record data updated from a row action pop-up

Zach- So I understand what you are doing with the list.render() and the updateDate(), do I want to set that up with a custom button on the pop-up so it would perform a save, close the window, then update the data in the list?  Any code example you can provide would be awesome or just a link to another post if you have already given an example before.

Thanks!
