自定义setter时，使用函数式组件声明时找不到onChange事件

自定义setter时，声明setter如果使用函数式组件，调用onChange事件时会报错找不到该方法,请问是什么原因？


Start by reproducing the custom setter declared with a functional component and invoking its onChange event, then trace where the event method is looked up. Done means the functional-component setter can invoke onChange without a missing-method error; the issue provides no files or tests to target.
