Nested Row Example with Backbone Models

[ckosmowski]

I'm trying to adapt the nested row example but with Backbone Models as items instead. Toggling the rows "on" works but when trying to toggle them "off" there are errors inside the setItem method because "original_object" is null. Something with the indexes here seems to be messed up. Could you have a look at this?

You can now toggle Backbone Models in the Nester Rows example via the "useBackbone" variable at the top. See https://github.com/globexdesigns/doby-grid/commit/7b9681172914c27e5038062ec053ec48ac035a0b
