title: 'v-if' does not work when added to the 'return' function. Why?
body: <p><code>v-if="css_max_count[i] == true</code> works fine, but if I add a <code>return</code>, then this code does not work. Any reasons?</p>
  
  <p>short code:</p>
  
  <pre><code>&lt;div class="ui form" v-for="(im, i) in sorted_listim"&gt; 
      &lt;div  class="ui left pointing red basic label" v-if="css_max_count[i] == true"&gt;
          {{im.count_buy}}
      &lt;/div&gt;
  
      &lt;div @click="add_dar(i)" class="ui right small basic green button" &gt;&lt;h3&gt;+&lt;/h3&gt;
      &lt;/div&gt;
  
  &lt;/div&gt;
  
  
  add_dar(i) {
      if (im.count_buy &lt; count) {
          this.css_max_count[i] = true
          // return - ??????
      } else this.css_max_count[i] = false
  }
  </code></pre>
