JavaFX 2.0 :: Modifying Item In Observable List Doesn't Update ListView

I am using:

Java:..... 1.8.0_20JavaFX:... 8.0.20-b26 

I have this class:
 
public class Person {
    private SimpleStringProperty name;
    public SimpleStringProperty nameProperty(){
        if(this.name==null){
            this.name=new SimpleStringProperty();

[Code] .....

I have this:

lista = FXCollections.<Person>observableArrayList();
lista.addAll(new Person("uno"),new Person("due"),new Person("tre"));
myListView.setItems(lista);

The problem is if I add /remove an item all is fine, the listView refreshes correctly:

Person p = new Person(tfld_textAdd.getText());
lista.add(0, p);
 
But if I change a value on an item into the observable list it doesn't:

lista.get(0).setName("new value");
 
I also have a table linked in the same way and the table workd correctly after I updated my Java version...
