I have tried to recreate the issue here that showed up when I upgraded from 1.2.1 to 1.2.2 of the aurelia-kendoui-bridge.
In my real solution I have created my own delegate for the navigate method in the scheduler so I can recreate the scheduler with different data (mainly so I can have grouping in timeline, but not the other views).
After talking with Jeroen on gitter this recreating of the scheduler was the solution I came up with and that seemed to work fine until I upgraded the bridge.
With 1.2.2 whenever I change view the header part of the grid does not seem to get destroyed, so after changing views I end up with multiple scheduler headers. If I in this gist change back to 1.2.1 in the index.html things get back to the way it used to be.
Another issue that I noticed here that might be due to my own error(?) and behaves the same in both versions is that I can't seem to change view when the view is to narrow and the view buttons gets grouped to a dropdown. In that case the navigate event seem to be hit with a changeView action as soon as I click on the view selector. Without my own k-on-navigate overload the dropdown works.
