JavaFX -- controller don't see the button or event - javafx

Question

Why, when I click to the "New" button, text are not change?
A Main class:
public class MainApp extends Application {
#Override
public void start(Stage primaryStage) throws IOException {
BorderPane rootLayout = FXMLLoader.load(getClass().getResource("view/RootLayout.fxml"));
AnchorPane code = FXMLLoader.load(getClass().getResource("view/DeskLayout.fxml"));
rootLayout.setCenter(code);
GridPane tool = FXMLLoader.load(getClass().getResource("view/ToolLayout.fxml"));
rootLayout.setBottom(tool);
primaryStage.setTitle("MyLittleIDE");
primaryStage.setScene(new Scene(rootLayout));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
ToolLayoutController:
public class ToolLayoutController {
#FXML
private Button newButton;
#FXML
protected void handleNewProject(ActionEvent event) {
newButton.setText("123");
}

I also try to make a sample application with javafx, and add toollayout.fxml only, controller and it works. But I can't do this on this case.
