如何使此JavaFX绑定多次触发？

import javafx.beans.binding.Bindings;
import javafx.beans.property.IntegerProperty;
import javafx.beans.property.SimpleIntegerProperty;

public class Main {
    public static void main(String[] args) {
        IntegerProperty property1 = new SimpleIntegerProperty(10);
        IntegerProperty property2 = new SimpleIntegerProperty(20);

        // 使用bindBidirectional方法进行双向绑定
        Bindings.bindBidirectional(property1, property2);

        System.out.println("property1: " + property1.get()); // 输出：property1: 20
        System.out.println("property2: " + property2.get()); // 输出：property2: 20

        // 修改其中一个属性的值
        property1.set(30);

        System.out.println("property1: " + property1.get()); // 输出：property1: 30
        System.out.println("property2: " + property2.get()); // 输出：property2: 30

        // 修改另一个属性的值
        property2.set(40);

        System.out.println("property1: " + property1.get()); // 输出：property1: 40
        System.out.println("property2: " + property2.get()); // 输出：property2: 40
    }
}
