body: <p>i have polymer template in which i have 3 divs . i want to keep condition on based on name m fetching in expression. How to keep condition for the same. 
  code is below:</p>
  
  <pre><code>&lt;div class="cySimplifiedContainer isCostLabel"&gt;
      &lt;span&gt;{{item.id.optnName}}&lt;/span&gt;
  &lt;/div&gt;
  &lt;div class="isSummary"&gt;
      &lt;span class="iSHeader"&gt;{{_toMoneyFormat(item.optnCtd)}}&lt;/span&gt;
  &lt;/div&gt;
  &lt;div class="isSummary"&gt;
      &lt;span class="iSHeader"&gt;{{_toMoneyFormat(item.optnGoFwd)}}&lt;/span&gt;
  &lt;/div&gt;
  &lt;div class="isSummary"&gt;
      &lt;span class="iSHeader"&gt;{{_toMoneyFormat(item.optnTotal)}}&lt;/span&gt;
  &lt;/div&gt; 
  </code></pre>
  
  <p>I need to keep check on item.id.optnName . If it contains KEFH then it should remove _toMoneyFormat function from span.
