The correct way of doing this is to supply your observable list with an "extractor" Callback. This will signal the list (and ListView) of any property changes.

Custom class to display:

public class Custom {
    StringProperty name = new SimpleStringProperty();
    IntegerProperty id = new SimpleIntegerProperty();

    public static Callback extractor() {
        return new Callback() {
            @Override
            public Observable[] call(Custom param) {
                return new Observable[]{param.id, param.name};
            }
        };
    }

    @Override
    public String toString() {
        return String.format("%s: %s", name.get(), id.get());
    }
}

And your main code body:

ListView myListView;
//...init the ListView appropriately
ObservableList items = FXCollections.observableArrayList(Custom.extractor());
myListView.setItems(items);
Custom item = new Custom();
items.add(item);
item.name.set("Mickey Mouse");
// ^ Should update your ListView!!!
