PWA - with Vue and Vuex

I'm having a problem rendering the list in real time on smartphones,

I get Vuex with computed:

produtosFiltrados() {
  return store.state.listaProdutos.filter((produto) => {
    let query = produto.nome.toUpperCase();
    return query.match(this.busca.toUpperCase())
  })
},

On the web the rendering is perfect only in smartphones with list locked, only the rendering works if I delete something in the search

BUSCAR POR NOME: 
<input type='text' v-model='busca' class='input inputText'>

Does anyone know how to get around this situation on my smartphone?
