    Error: Expected spy updateFromForm to have been called.

It's because the spy is being called in the wrong context. Also, you should never be using '.init' - always use 'new'. Have a look at Spine's model tests for a way to proxy the spy context.

Ups. Using new now.

The spy is set on users instance (in the spec) as well as on user instance (in the beforeEach block). So the spy is set-up correctly. Or I am missing something?

@maccman, the weird thing is that when I manually users.el.delegate, it does work. So the event is triggers successfully and handled.
I must be missing something stupid when defining it with Spine.

@maccman, you're right. When updateFromForm is called as event handler - it is proxied, so that the actual function is hidden and can't be replaces (spied on).
The only way to avoid that - is to make a dummy function onBlur for event handlers and call the actual function from there.
