Get model for listview click event

Is there any way to retrieve the model that used to render the listitem?

For example, my model have 3 fields, A B and C. When I render the listitem, I just used bindId for A and B. I want to be able to get the C value when handling onClick event. However, if I use e.section.getItemAt(e.itemIndex), it only gives me the data that used to render the view, which is A and B in this case. I want to retrieve the model's data instead of only the ones that used for rendering the view.

Any thought on that? Thanks!
