ion-slide-box update()问题

songjimin1994

控制台弹出警告：
“Delegate for handle "XXXXX" could not find a corresponding element with delegate-handle="XXXXX"! update() was not called!
Possible cause: If you are calling update() immediately, and your element with delegate-handle="XXXXX" is a child of your controller, then your element may not be compiled yet. Put a $timeout around your call to update() and try again.”
后来根据提示，加上了定时器，但是明明已经进入定时器了，但是还是依旧会弹出这个错误提示，是为什么呢？该怎么优化呢？
请各位大神教教我！！！！谢谢~~~
