JavaFX: TableView couldn't edit with FXML

I am currently developing a JavaFX Application with FXML that includes a TableView. I could not figure out how to use StringConverter<T> in the TextFieldTableCell<S,T>. I've done some code so far. It returns an Exception when texfield value saving to the cell;

This is my source...

    @FXML
    private TableColumn<Customer, Integer> columnID;

    columnID.setCellFactory(
                    new Callback<TableColumn<Customer, Integer>, TableCell<Customer, Integer>>() {
                        StringConverter<Integer> converter;

                        @Override
                        public TableCell<Customer, Integer> call(TableColumn<Customer, Integer> list) {
                            return new TextFieldTableCell<>(converter);
                        }
                    }
            );

And it returns this Exception...

Exception in thread "JavaFX Application Thread" java.lang.IllegalStateException: Attempting to convert text input into Object, but provided StringConverter is null. Be sure to set a StringConverter in your cell factory.

Another simple solution

columnID.setCellFactory(TextFieldTableCell.forTableColumn());

I found the solution. This is my solution...

columnID.setCellFactory(
                new Callback<TableColumn<Customer, Integer>, TableCell<Customer, Integer>>() {
                    StringConverter<Integer> converter;

                    @Override
                    public TableCell<Customer, Integer> call(TableColumn<Customer, Integer> list) {
                        return new TextFieldTableCell(new NumberStringConverter());
                    }
                }
        );
