title: Why v-model doesn't work with an array and v-for loop?
body: <p>I got a custom select component, it works with a simple variable, but when used with v-for it won't work:</p>
  
  <p><a href="https://jsfiddle.net/7gjkbhy3/19/" rel="noreferrer">https://jsfiddle.net/7gjkbhy3/19/</a></p>
  
  <pre><code>&lt;select2 v-for="item, index in samples" v-model="item" &gt;&lt;/select2&gt;
  data : { samples : [0, 0, 0]}
  </code></pre>
  
  <p>This works:</p>
  
  <pre><code>&lt;select2 v-model="sample"&gt;&lt;/select2&gt;
  data : { sample : 0}  
  </code></pre>
  
  <p>what am I missing here?</p>
