Currently, there's a global postRender process, it works like a charm, but I think there's missing something. A postRender for Promises, like a callback.

To justify this proposition, here's a case :

Lets say we have an "AddToCalendar" link inside each views row. 
So when we call theme_view, theres nothing we can do to add an event on each links.
Global postRender is of course triggered before the view query. We could add a jQuery ".on()" function on body, but it's not really interesting since my solution here solve that problem.

What do you think?

It could be useful to have the views results. We could want to manipulate something with data.attributes or even check what the view's output is to make something if its empty or not.
