detail Expand contains undefined events

[George]

Hi!

I am unable to retrieve the e.data.id because events from detailExpand is undefined. For detailInit, it's okay. Do you know why? Is there a bug or is this written in this way?

                detailInit: function(e) {
                            console.log(e.data.id);
                },
                detailExpand: function(e) {
                             console.log(e.data.id);
                 },
