Hello Stefan,
There was an issue with the switch not changing its style when toggled in the 2013.2.1021 version, this issue has been resolved in the latest version, so you should stick with it. As for the error that you are getting:
Object # <Object> has no method "appLevelNativseScrolling"
This does not seem to be related to the Kendo UI framework, as there is no such method implemented. But it looks like a typo made with calling the method, did you try with "appLevelNativeScrolling" (removing the "s" in the Native)?
