I suggest you that you see angular.js tern plugin. There is complex case.To
manage return value with tern, you can :

1) hard coded the returns value (as you have done with -> fn())
2) use -> !this if your return value is the same instance than your
function property
3) use +MyType if your function must returns an instance of MyType that you
have declared.
4) use custom!MyFunction where MyFunction is registered with
infer.registerFunction("MyFunction", ...
With that you can develop your own JS logic. See angular_bind for instance.

Have you tried to use Event+ in your tern plugin? If you see jquery.json
tern def, it use Element too and it is not declared in the jquery.json but
in the browser.json
