Vue.js modal component example not closing - vue.js

Question

I'm trying to use Modal Component Example from Vue.js website examples in my project. When I use the modal component in my-project component, it works fine, but when I add a close button in the header slot, this button doesn't work, it doesn't close the modal while the default button in the footer still works fine.
The modal component :
<template>
<transition name="modal">
<div class="modal-mask">
<div class="modal-wrapper">
<div class="modal-container">
<div class="modal-header">
<slot name="header">
default header
</slot>
</div>
<div class="modal-body">
<slot name="body">
default body
</slot>
</div>
<div class="modal-footer">
<slot name="footer">
default footer
<button class="modal-default-button" #click="$emit('close')">
OK
</button>
</slot>
</div>
</div>
</div>
</div>
</transition>
</template>
<script>
export default {
props: {
showMal: Boolean
}
}
</script>
<style scoped>
<!-- same as vuejs website modal component example -->
</style>
How I'm calling it :
<template>
<button id="show-modal" #click="showModal = true">Show Modal</button>
<!-- use the modal component, pass in the prop -->
<modal v-if="showModal" #close="showModal = false">
<!--
you can use custom content here to overwrite
default content
-->
<div slot="header">
<button class="modal-default-button" #click="$emit('close')">Close</button>
</div>
</modal>
</template>
<script>
export default {
data () {
return {
showModal: false
}
}
</script>
What's wrong in my implementation of this code ?

Answer 1

Since this is at the parent:
<template>
<button id="show-modal" #click="showModal = true">Show Modal</button>
<!-- use the modal component, pass in the prop -->
<modal v-if="showModal" #close="showModal = false">
<!--
you can use custom content here to overwrite
default content
-->
<div slot="header">
<button class="modal-default-button" #click="$emit('close')">Close</button>
</div>
</modal>
</template>
This code:
<button class="modal-default-button" #click="$emit('close')">Close</button>
Actually makes the parent emit the 'close', not the modal child.
So, since the property that controls the modal is showModal, just set it to false instead:
<button class="modal-default-button" #click="showModal = false">Close</button>
