[bug?] When I try to read listener(onXXX) from $props, I got the undefined.

[JuerGenie]

1. on tutorial/#step-13
2. edit file App.vue, add function function test() {} and add bind <ChildComp @response="test" />.
3. edit file ChildComp.vue, and add <div v-if="!!$props.onResponse">{{ String($props.onResponce) }}</div>

just only got rendered html: <!-- v-if -->, not <div>function test() {}</div>.
on [email protected] it worked, but now it not work.

why and how? 😂

First of all, in part 3 edit file ChildComp.vue, and add <div v-if="!!$props.onResponse">{{ String($props.onResponce) }}</div>, the String($props.onResponce) should be String($props.onResponse), if you want get the onResponse, you must declare in the props😉.
