Vuejs modal component passing data - vue.js

Question

I am stuck making a modal component for my app in VueJS. I want to be able to put it in its own component for reusability, be able to pass custom content and have multiple modals.
I made the component and it looks like this from the VueJS docs:
Modal.vue
<template>
<div ref="modal">
<script type="text/x-template" id="modal">
<transition name="modal">
<div class="modal-mask">
<div class="modal-wrapper">
<div class="modal-container">
<div class="modal-header">
<slot name="header">
Header
</slot>
</div>
<div class="modal-body">
<slot name="body">
Body
</slot>
</div>
<div class="modal-footer">
<slot name="footer">
Footer
</slot>
<button class="btn btn-primary" #click="$emit('close')">
Button
</button>
</div>
</div>
</div>
</div>
</transition>
</script>
</div>
</template>
<script>
export default {
components: { },
props: ['header', 'footer', 'body', 'button'],
data: () => ({
showModal: false
}),
methods: {
open () {
console.log('Opening modal')
this.showModal = true
}
}
}
</script>
<style>
#modal {
/*color: #000;*/
}
.modal-mask {
position: fixed;
z-index: 9998;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, .5);
display: table;
transition: opacity .3s ease;
}
.modal-wrapper {
display: table-cell;
vertical-align: middle;
}
.modal-container {
width: 300px;
margin: 0px auto;
/*padding: 20px 30px;*/
background-color: #25262D;
color: #FEFEFE;
border-radius: 3px;
box-shadow: 0 2px 8px rgba(0, 0, 0, .33);
transition: all .3s ease;
font-size: 1.2em;
}
.modal-header {
border-radius: 3px;
background-color: #202128;
border: none;
}
.modal-header h3 {
margin-top: 0;
color: #42b983;
}
.modal-body {
margin: 20px 0;
/*background-color: #202128;*/
border: none;
}
.modal-footer {
text-align: center;
border: none;
}
.modal-footer .btn {
font-size: 1.0em;
}
/*
* The following styles are auto-applied to elements with
* transition="modal" when their visibility is toggled
* by Vue.js.
*
* You can easily play with the modal transition by editing
* these styles.
*/
.modal-enter {
opacity: 0;
}
.modal-leave-active {
opacity: 0;
}
.modal-enter .modal-container,
.modal-leave-active .modal-container {
-webkit-transform: scale(1.1);
transform: scale(1.1);
}
</style>
I add a modal in my App.vue:
<button #click="openUpdatedModal()" type="button" class="btn btn-default" data-toggle="modal" data-target="#modal">
Launch Updated Modal
</button>
<modal ref="updatedModal" v-if="showModal" #close="showModal = false">
<!--
you can use custom content here to overwrite
default content
-->
<div slot="header">custom header</div>
</modal>
<script>
import Modal from './components/Modal'
export default {
components: { Modal },
data: () => ({
showModal: false
}),
methods: {
openUpdatedModal () {
this.$refs.updatedModal.open()
}
}
}
</script>
When I click the button I get the text in console "Opening modal" but nothing happens.
I can summon it and it works if I have ALL the code in App.vue
What am I missing?

I made it work by creating a ModalComponent.vue and removing the script tag as Phil suggested in the comments. Here's the code.
ModalComponent.vue:
<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{
}
</script>
Here's how I defined my component:
Vue.component('modal', ModalComponent);
Modal button in markup:
<button id="show-modal" #click="showModal = true">Show Modal</button>
And the modal component being called on the page:
<modal v-if="showModal" #close="showModal = false">
<!--
you can use custom content here to overwrite
default content
-->
<h3 slot="header">custom header</h3>
</modal>
It's worth noting that I had to declare the showModal property wherever I use my modal.
