Maybe I'm just missing something, but is there no way to deal with arrays? You know, like looping through data and displaying things for each of them? (also related: what about looping through Object.keys()?)
What about dates? And data parsing/formatting in general?
Those are kind of important for a bi-directional bindings library. Remember that the Javascript data is usually the canonical data and the displayed data is derived from it, not the other way around.
If you want to compare w/ Knockout/Angular/etc then there's even more stuff that could be considered as "missing" (e.g. condiditionals, partials/components, how-do-i-use-select2-with-it, etc). One could argue those are out of scope for a lightweight library, but then again, I think this library has too many dependencies for something that advertises itself as "lightweight".
My own framework Mithril ( http://lhorie.github.io/mithril ) for example is ~5kb gzipped, has no dependencies, and allows you to do quite a bit more in terms of templating and data binding.
Incidentally, I wrote a article a while back about how two-way binding isn't even always the best answer to your questions, and that there are often better ways to update javascript data from forms: http://lhorie.github.io/mithril-blog/asymmetrical-data-bindi...
