Problem with my JTable Personalized, it does not recognize me when a cell changes its value

I commented to them about a problem that came up, I decided to create a JTablePersonalizado, to facilitate the change of colors of cells, of the heading, that the text is centered, but my problem is that when I obtain, the model of the table, so that I can recognize a change of some value in some cell, I launch an event.

This would do it like this:      tabla.getModel.addTableModelListener (this);

The problem is that in doing so, it does not detect events, whereas if I do it with a normal JTable, it does.

NOTE: The DefaultTableModel, I also modify it in another class so that only some cells can be edited.
