title: How to v-model 2 values?
body: <p>I was using buefy <code>&lt;b-autocomplete&gt;</code> component and there is one property called <code>v-model</code> which is binding values to the input field</p>
  
  <p>now I wanna bind Full Name into the field but the data consist with <code>list[index].first_name</code> and <code>list[index].last_name</code>, and the <code>index</code> is from a <code>v-for</code> loop. </p>
  
  <p>Since <code>v-model</code> cannot bind a function (it has specific index so I cannot just concat it on <code>computed</code> then pass it on) so it's either <code>v-model="list[index].first_name"</code> or <code>v-model="list[index].last_name"</code></p>
  
  <p>How do I make it bind's these two?</p>
