title: Binding method result to v-model with Vue.js
body: <p>How do you bind a method result to a v-model with Vue.js?</p>
  
  <p>example :</p>
  
  <pre><code>&lt;someTag v-model="method_name(data_attribute)"&gt;&lt;/someTag&gt;
  </code></pre>
  
  <p>I can't make it work for some reason.</p>
  
  <p>Thank you.</p>
