So I thought about the button component, but i don’t know how to creat button’s invoke method dynamically,
the invoke method is like this :

 public void onButton_1Click(Component source) {
}

the button creat like this:
Button btn1=componentsFactory.createComponent(Button.class);

but the btn1 don’t have like this method: btn1 .setInvoke()

Use the setAction() method instead.

For example:

Button button = componentsFactory.createComponent(Button.class);
button.setAction(new BaseAction("sayHello") {
    @Override
    public void actionPerform(Component component) {
        showNotification("Hello!");
    }
});

Or:

<actions>
    <action id="sayBye" invoke="sayBye"/>
</actions>

@Inject
private Action sayBye;

@Override
public void init(Map<String, Object> params) {
    Button button = componentsFactory.createComponent(Button.class);
    button.setAction(sayBye);
}

public void sayBye() {
    showNotification("Bye!");
}
