I can not notify update in observable list to ListView.

    @Test
    public void testUpdate() {

        ObservableListWrapper<Long> list = new ObservableListWrapper(new LinkedList<Long>()) {
            // Just for test
            @Override
            public void sort() {
                callObservers(new NonIterableChange.SimpleUpdateChange(0, this));
            }
        };
        Long x = 1L;
        list.add(x);

        ListView<Long> listView = new ListView<Long>(list);
        listView.setCellFactory(new Callback<ListView<Long>, ListCell<Long>>() {
            @Override
            public ListCell<Long> call(ListView<Long> param) {
                return new ListCell<Long>() {
                    @Override
                    protected void updateItem(Long item, boolean empty) {
                        super.updateItem(item, empty);
                        System.out.print("Update");
                    }
                };
            }
        });

        list.sort(); // Must output Update, nothing happens
    }

As workaround we can remove and then add item
