You are right, my class didn't derived from TObject.

No I didn't. It was my first question, I wanted to know if I had to create an OnDisconnect. But I didn't say all about my code so I appologize 

The object assigned to the Data property

So the onlye thing I needed to do is to add ": public TObject" to my class.
