Your itemRenderer must update a property on the dataProvider item. Further, it must use this property to set the checkbox checked state in set data or commitProperties. Search the archives for renderer recycle for more info on that.
Find an example of a checkbox renderer. Alex Harui has one on his blog, I believe, and I think there is one on www.cflex.net <http://www.cflex.net/> . Google will find more. Getting a renderer right is a bit complicated, so don't try it from scratch.
