In my Mvc Controls Toolkit I developed Helpers based on the knockout library. These helpers not only help in writing the knockout code, but enhance the knockout library with Unobtrusive validation and globalization. Moreover, the binding mechanism is enhanced to include complex controls such as a DatetimePicker, and other "complex" (made by different html parts) controls.
Finally, knockout templates can be defined through Razor helpers.
See the documentation here, here, here and here. I also have some tutorials that show how to implement advanced features with my helpers:
