I replied to the same question in a support ticket from your colleague. For your convenience, I am pasting the answer here, too.
If I understand your case correctly, in 1324, the passed object (in fact, undocumented and more or less present by coincidence) is actually the view model instance. You can test that with `console.log(e == this);`. You can safely use `this` instead, as this approach is documented and works with 716 version too.
