creator3.x api问题

public onAddEvent(btnDisplay: Node, callback: Function, transition: number = Button.Transition.COLOR) {
    // let btn: Button = btnDisplay.getComponent(Button) || btnDisplay.addComponent(Button);
    // btn.transition = transition;
    Logger.log("onAddEvent==", btnDisplay)
    // btnDisplay.targetOff(btnDisplay);
    btnDisplay.on(Node.EventType.TOUCH_START, () => {
        Logger.log("onAddEvent=1=", btnDisplay)
        // if (btn.enabled) {
            //加点击音效
            // AudioHelper.play_click()
            callback && callback();
        // }
    }, btnDisplay);
    btnDisplay.on(Node.EventType.TOUCH_END, () => {
        Logger.log("onAddEvent=2=", btnDisplay)
        // if (btn.enabled) {
            //加点击音效
            // AudioHelper.play_click()
            callback && callback();
        // }
    }, btnDisplay);
}

这样子监听的点击为啥没反应了呢？3.x改动好大，可怕
