angular2（ionic2）：在ios中，某个懒加载页面上的所有click事件不触发变化检测？

Question

最近在运用ionic2的开发中，遇到了一个“奇怪”的事情：某个页面中，有用click事件来改变页面元素中的a标签的active(一个class)来控制元素是否选中。在浏览器和android实机中工作正常，可是到了ios实机中，a标签不会变化。debug发现在ios上click事件中的所有代码都执行了，但是页面没有刷新。于是在每个click的事件代码的最后加上this.changeDetectorRef.detectChanges(),手动让这个页面执行变化检测，问题解决。但问题是，按照angular2的特性，所有的click事件都应该会自动触发整个组件树的变化检测，为什么这个页面在ios中失效了，有哪位大神知道原因吗？
