I already replied about this for your question in learn section.

Put print in ctor call and you'll see it most likely does works. 
Or put a null check on D side, just whatever. Do proper debug, 
don't just guess.

Most likely it isn't working because you have wrong translation.
D classes have virtual by default methods, and your C++ method 
isn't virtual, so mark it 'final' on D side and this should fix 
the problem.
