What is two way binding?
...k to the model.
Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.
In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "...

The inversion number of a sequence is one...
