Bing Maps API - How can I pass extra parameters to the GeoCodeCallback

Question

I've been banging my head against my desk with this problem. I've got the below code working properly, however what I WANT to be able to do is add my custom Title to the newShape.SetTitle(title) and my custom Desc to the newShape.SetDescription(desc)

I have tried adding the "title" and the "description" to the GeoCodeCallback function like this function GeocodeCallback(shapeLayer, findResults, places, moreResults, errorMsg, title, desc) but it just makes it so that all of the other parameters are broken.

Can anyone lend a helping hand on this?

        { "addr": "12 Bowridge Dr NW, Calgary, Alberta, Canada", "title": "RockPointe Bowridge", "desc": "Here is a RPC site" }

        map.AddShape(newShape);
