In JavaFX and scenebuilder project, how to use the setOnAction() method in Controller class

I am new to JavaFX and SceneBuilder.
I created an app using the SceneBuilder in Eclipse. (Right click FXML file > open with SceneBuilder)
Inside initialize method, I can not see the setOnAction method.

package application.controller;

import com.jfoenix.controls.JFXPasswordField;
import com.jfoenix.controls.JFXTextField;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.scene.image.ImageView;

public class controller {

    

    @FXML
    private ResourceBundle resources;

    @FXML
    private URL location;

    @FXML
    private JFXTextField loginID;

    @FXML
    private JFXPasswordField passwordID;

    @FXML
    private ImageView loginButton;

    @FXML
    public void initialize() {
        loginButton.setona
        
    }
    
    
    
}

>Solution :

You defined loginButton as an ImageView. ImageView does not have setOnAction method. use setOnMouseClicked instead.
