title: get Select option text with VueJs
body: <p>I have a classic <code>&lt;Select&gt;</code> input, and I want to get the text of the selected element. I am able to get the value, but not the text:</p>
  
  <pre><code>&lt;select v-model="ageCategory" class="form-control" @change="calculateCategoryName"&gt;
      &lt;option value="0"&gt;{{trans('core.no_age')}}&lt;/option&gt;
      &lt;option value="1"&gt;{{trans('core.children')}}&lt;/option&gt;
      &lt;option value="2"&gt;{{trans('core.teenagers')}}&lt;/option&gt;
      &lt;option value="3"&gt;{{trans('core.adults')}}&lt;/option&gt;
      &lt;option value="4"&gt;{{trans('core.masters')}}&lt;/option&gt;
      &lt;option value="5"&gt;{{trans('core.custom')}}&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I can get value with : </p>
  
  <pre><code>var ageCategory = this.ageCategory;
  </code></pre>
  
  <p>But I can't get text... Any idea how should I do it???</p>
