I solved it. Apparently you have to store the vtkEventQtSlotConnect object otherwise the signals will not be delivered.  
So basically this line is incorrect:

```auto
vtkNew<vtkEventQtSlotConnect> eventQtSlotConnect;

```

and should be changed to something that is stored permanently. For example a member variable of your class.
