Reset filtered data Vue.js

I need to implement a button that would drop the filters in my application. The application is written on Vue. The filters themselves were implemented, but I do not know how to implement their reset.

<template>
  <div id="app">
    <input type="text" v-model="search">
    <select name="sort" v-model="sort">
      <option v-for="option in options" :value="option.value" :label="option.label"></option>
    </select>
    <table>...</table>
  </div>
</template>

<script>
  import goodsList from './api/data';

  export default {
    name: 'app',
    data() {
      return {
        search: '',
        sort: '',
        options: [
          { label: 'Default', value: 'none' },
          { label: 'Brand', value: 'brand' },
          {label: 'Price', value: 'price'}
        ],
        goods: goodsList,
      }
    },
    computed: {
      filteredList() {
        let filteredGoods = this.goods.filter( item => {
          return item.name.toLowerCase().includes(this.search.toLowerCase());
        });
        switch (this.sort) {
          case 'brand':
            filteredGoods.sort((a, b) => a.brand.localeCompare(b.brand));
            break;
          case 'price':
            filteredGoods.sort((a, b) => parseInt(a.price - b.price));
            break;
        }
        return filteredGoods;
      }
    },
  }
</script>

You will need a reset function which will assign the default selected value eg: 'none' to the v-model 'sort'. Since it is a two way binding, changing the value of 'sort' variable will eventually reset the selected option.

Function to be added: 

resetOptions: function () {  
  this.sort='none';

}
