For VSTO Add-In Application we do have ContentControlOnEnter and ContentControlOnExit events, to perform post change operation of ContentControl
But, I can't see any such events in office JS API
Do, we have any other way to achieve similar functionality, my goal is to detect changes of ContentControl and update into pane of Add-in immediately, right now we have to refresh UI manually to update changes of ContentControls to UI, which is big usability drawback for us.
Please suggest any options.
