JavaFX 2.0 :: Why Bind Of Width Of TableColumn Is Not Working

I would like to bind the width of the second column of my TableView with the width of my TableView.
My custom TableView class :

public class CustomTableView<T> extends  
TableView<ObservableList<Pair<String, Object>>> implements Cloneable {  
private static Logger logger = Logger.getLogger(CustomTableView.class);  
private double prefWidth; // optionnel   private double minWidth; // optionnel  
private double maxWidth; // optionnel   private double height; // optionnel  
private List<InfoColumnBean> cols; // optionnel 

[Code]....
