Mouse Hover in VueJS component implementation in Laravel

I am a beginner in Implementing laravel with vue and i am having a hard time figuring what i have wrong

My Mouse hover is not working when i am using it on laravel. My vue file is stored in resources/js/Dashboard.vue

What i tried so far is. Change v-on:mouseover with @mouseover but it still not working.

The Result is that when i hover the button it doesn't change texts.Can someone please help me in resolving what i had done wrong?

Dashboard.vue

<template>
<div id="mouse">
  <a
    v-on:mouseover="mouseover"
    v-on:mouseleave="mouseleave">
    
  </a>
</div>
</template>
<!--Force Override of the css style for datepicker class-->

<style>

  #mouse {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    display: block;
    width: 280px;
    height: 50px;
    margin: 0 auto;
    line-height: 50px;
    text-align: center;
    color: #fff;
    background: #007db9;
  }
</style>

<script>

export default {
    components: {
    },
    data() {
        return {
          showAudience: false,
          message: 'Hover Me',
        }
    },
    computed: {
    },
    methods : {
    mouseover: function(){
      this.message = 'Good!'
    },    
    mouseleave: function(){
      this.message = 'Hover Me!'
    }
    },
    mounted() {
    },
}
</script>

Blade.php

@extends('layouts.app', ['pageSlug' => 'dashboard'])

@section('content')
  <dashboard-component></dashboard-component>
  @endsection

@push('js')
    <script src="/js/plugins/chartjs.min.js"></script>
    <script src=""></script>
    <script>
        $(document).ready(function() {
          //demo.initDashboardPageCharts();
        });
    </script>
@endpush

package.json just in case someone needs to look at it
