One of the devs of scalejs here. We tried integration with kendo ui but found other libraries did what kendo did for free, and some even done better. We actually have some kendo examples, but there isn't a kendo extension as of yet. I am pretty sure you could easily use Kendos binding Library, but for consistency it would make more sense to use knockout because of the binding class provider (e.g. bindings) as it allows for separation of large bindings (e.g. configurations for advanced UI controls).
If you have any questions feel free to email me at egucciar@gmail.com. there's a website with some documentation and learning resources at http://www.scalejs.com. there's nothing there yet for making your own extensions but its not very hard. We have a lot of extensions you can use as references.
