How to turn on the function hints on command line?

Im using mathlab 2016a. On the command line function hints will not list available commands and functions. As an example(my commands):

 load fisheriris;
 X=meas;         % Inputs
 Y=species;      % Targets
 bc=NaiveBayes.fit(X,Y);

Now when i type "bc." on command line and it doesn't show function lists as you can see on this photo. This photo has been taken from a studying video with matlab 2013a(I think):

I visited this article but the problem is available yet.

What toolbox is NaiveBayes in? It doesn't seem to be in my Statistics and Machine Learning Toolbox.

Try typing a tab right after you hit dot and see if that brings up the list of properties and methods.
