JavaFX FXML doesn't see my controller methods correctly "Controller is not defined on root component" when using fxml as component within fxml

Question

I'm creating rich ui application and I use FXML within FXML and every part have separate controllers. I decided to follow this tutorial and use my fxml as component. So I use class as a controller and component. Everything seems to be working but I hit a wall when I try to put methods into my class/controller. I edited my FXML so I don't put controller directly into it. But using class itself. this is where the problematic line is

<fx:root fx:id="profilePane" onMouseClicked="#select" onMouseEntered="#hoverOver" onMouseExited="#hoverOut" type="javafx.scene.layout.Pane" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">...etc

every method is red saying that Controller is not defined on root component well I know that I removed that part from my fxml. But how would it work on tutorial that I follow? Here is my component class what I work with

imports etc..
public class FxmlProfilePanel extends Pane implements Initializable{

    @FXML
    private ToggleButton toggleButton;

    @FXML
    private Pane profilePane;

    private FadeTransition fadeTransition=new FadeTransition(Duration.millis(500),toggleButton);


    /**
     * Initializes the controller class.
     */
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO


        System.out.println("Is fx thread?:"+Platform.isFxApplicationThread());
    }   

    public FxmlProfilePanel(){
        FXMLLoader fxmlLoader=new FXMLLoader(getClass().getResource("/bitcompile/ecps/fxml/FxmlProfilePanel.fxml"));
        fxmlLoader.setRoot(this);
        fxmlLoader.setController(this);
        try {
            fxmlLoader.load();
        } catch (IOException ex) {
            Logger.getLogger(FxmlProfilePanel.class.getName()).log(Level.SEVERE, null, ex);
        }
    }


    public void hoverOver(MouseEvent event){
        Platform.runLater(() -> {
            if(!toggleButton.isSelected()){
            toggleButton.setText("Select profile");
            fadeTransition.setFromValue(0);
            fadeTransition.setToValue(1.0);
            fadeTransition.play();

            }else{
            toggleButton.setText("Deselect profile");
            fadeTransition.setFromValue(0);
            fadeTransition.setToValue(1.0);
            fadeTransition.play();
            }
        });
    }

      public void hoverOut(MouseEvent event){
        Platform.runLater(() -> {
            if(toggleButton.isSelected())
            fadeTransition.setFromValue(1.0);
            fadeTransition.setToValue(0);
            fadeTransition.play();
        });
    }

    public void selected(MouseEvent event){
        if(!toggleButton.isSelected()){
          toggleButton.setSelected(true);
          toggleButton.setText("Profile Selected");

        }else{
            toggleButton.setSelected(false);
            toggleButton.setText("Select profile");
        }
    }
}

So question is.When I use fxml/controller as component inside another fxml which is within another fxml etc. how do I connect my methods from within my component class? (I know how to do all this following normal fxml style with separate controller etc, but not this way).. Did I pick the wrong way of doing this? Should I consider another approach? thx for any insight.

full fxml code:

It works quite well with:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class LoadOwnFXML extends Application {

    @Override
    public void start(Stage primaryStage) {


            Scene scene = new Scene(new ProfilPane());
            primaryStage.setTitle("Hello World!");
            primaryStage.setScene(scene);
            primaryStage.show();
    }

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

}

And the ProfilePane class

import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.layout.AnchorPane;

public class ProfilPane extends AnchorPane {

    public ProfilPane() {
        try {
            FXMLLoader loader = new FXMLLoader(getClass().getResource("my.fxml"));
            loader.setRoot(this);
            loader.setController(this);
            loader.load();
        } catch (IOException ex) {
            Logger.getLogger(ProfilPane.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    @FXML
    public void select() {
        System.out.println("selected");
    }

    @FXML
    public void hoverOver() {
        System.out.println("hovered");
    }

    @FXML
    public void hoverOut() {
        System.out.println("hovered out");
    }
}
