Hi Dimiter & Dimo,
thanks for your workaround, binding it during the edit event was the crucial point. This seems to work as intented.
I'm looking forward to the Q1 2016 release where this'll be fixed, since the workaround is not optimal for us because we're using MVVM, so getting DOM elements with JQuery is not really best practice :)
But until the fix is live, this'll do!
