JavaFX ошибка взаимодействия с графическими элементами из контроллера

В окне не выводится сообщение, кнопка addWord работает, слово уходит, но не отображается на экране.

import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.scene.control.ListView;
import javafx.scene.control.TextField;

public class Controller {
    @FXML
    private TextField inputField;

    @FXML
    private ListView<String> listView;
    private final ObservableList<String> wordlist= FXCollections
            .observableArrayList("Привет", "Я","Тата");

    @FXML
    public void initialize() {
        listView=new ListView<>();
        listView.setItems(wordlist);
    }

    @FXML
    public void addWordToList(){
        String word=inputField.getText();
        listView.getItems().add(word);
        inputField.clear();
    }
}

Класс запуска:

public class Launcher {
    public static void main(String[] args) { Main.main(args);
    }
}

Класс приложения:

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {
    public final String PATH_TO_FXML= "sample.fxml";
    @Override
    public void start(Stage primaryStage)throws Exception{
        Parent root= FXMLLoader.load(getClass().getResource(PATH_TO_FXML));
        primaryStage.setTitle("Lesson4");
        primaryStage.setScene(new Scene(root));
        primaryStage.show();
    }

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