jtemplates

Can you use jTemplates for "Two-way bindings"?

Hi all.. Just toyed around with jTemplates today, and I love the idea. I was hoping I could find something similar to the data-binding model of WPF in it though, but so far I'm out of luck. Are anyone aware of such a model/framework? [EDIT] To clarify, I'd like something like MVVM, where I can have a back-end datasource in json format...
