I was looking into a problem similar to this a few days ago. I noticed in the Repeater.as framework code, that it ignores changes to the dataProvider collection that are of type CollectionEventKind.UPDATE. Thus, if you modify an item in the underlying data provider, the repeater will not update. If you add/remove an item, it will update.
