添加补间.js后不会触发按钮单击事件

当我添加代码行以补间显示框时，单击事件将不再触发。我的控制台中没有收到任何错误。如何解决我的问题？我做错了什么？

 createjs.Tween.get(directionsbox, { loop: false }).to({ x:800, y: 650 }, 4000)

  var directionsbox = new createjs.Container();
                displaybox = new createjs.Shape();
                displaybox.graphics.beginFill("#D8D8D8").drawRoundRect(0, 0, 800, 570, 2);

                var label = new createjs.Text("'Congratulations!  'n 'nYou have Completed a three levels." + "'n 'nYour score: " + totalScoresFromAllLevels + "'n 'nYour sccore was submited to the Arcade. 'n'n'nPlay again? Click here.", "bold 20px Arial", "#000");
                label.textAlign = "left";
                label.lineWidth = 540;
                label.y = displaybox.y + 5;
                label.x = displaybox.x + 10
                directionsbox.addChild(displaybox, label);
                self.stage.addChild(directionsbox);
