ListView is not reflecting changes

Question

I created a TableView a while back and registered Properties to each of the TableColumns. Editing of the internal data reflected itself back in the TableView just fine.

Here is sample how make listview with custom objects:

public class JavaFX_ListView extends Application {

    class MyObject {
        String day;
        int number;

        MyObject(String d, int n) {
            day = d;
            number = n;
        }

        String getDay() {
            return day;
        }

        int getNumber() {
            return number;
        }

        @Override
        public String toString() {

            return number + " " + day;
        }
    }

    ObservableList myList;

    // Create dummy list of MyObject
    private void prepareMyList() {
        myList = FXCollections.observableArrayList();
        myList.add(new MyObject("Sunday", 50));
        myList.add(new MyObject("Monday", 60));
        myList.add(new MyObject("Tuesday", 20));

    }

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("sample");
        prepareMyList();
        ListView listView = new ListView<>();
        listView.setItems(myList);

        Pane root = new Pane();
        root.getChildren().add(listView);
        primaryStage.setScene(new Scene(root, 300, 250));
        primaryStage.show();
        // testing
        Timer timer = new Timer();
        timer.schedule(new UpdateListTask(), 1000, 1000);
    }

    public static void main(String[] args) {
        launch(args);
    }

    // testing
    public class UpdateListTask extends TimerTask {
        @Override
        public void run() {
            Platform.runLater(new Runnable() {

                @Override
                public void run() {
                    myList.add(new MyObject("sample", Calendar.getInstance()
                            .getTime().getSeconds()));
                }
            });
        }
    }

}
