JavaFX 2.0 :: Filtering ListView By Selected Date

I'm trying to add filtering content in ListView by selected date from DatePicker. Every position(movie) has it's emission date saved, so when you choose date that you're interested in, it will show just matching titles. I was trying to use this solution:

@FXML
  private void initialize() {
  titleList.setCellFactory((list) -> {
  return new ListCell<Movie>() {
  @Override
  protected void updateItem(Movie item, boolean empty) {
  super.updateItem(item, empty);

[Code] ....
 
But when I add new position and change date, that I'm filtering by, every title disapear and don't reload. How can I make this work with every change?
