It works for me on iOS 8.3 on an iPad Air 2, building with PhoneGap Build instead of Intel XDK (can't seem to get the XDK to accept my certificate right now). In theory both build a Cordova app so this suggests C2's code is correct and perhaps the XDK build settings are incorrect or there is a bug in the Intel XDK itself. I'd recommend taking this up with Intel if you still have trouble.
