title: Use Function in {{ }} sintax
body: <p>Is it possible to use a function, like toLocaleLowerCase(), inside {{ }}?
  If not, is there another method to do this?</p>
  <pre><code>&lt;div *ngFor=&quot;let item of elements| keyvalue :originalOrder&quot; class=&quot;row mt-3&quot;&gt;
      &lt;label class=&quot;col-md-4 offset-md-2 my-auto&quot;&gt;{{item.key}}:&lt;/label&gt;
      &lt;input type=&quot;text&quot; class='col-md-4 my-auto' formControlName={{item.key.toLocaleLowerCase()}} value={{item.value}}/&gt;
  &lt;/div&gt;
  </code></pre>
  <p>Any help would be appreciated.</p>
  <p>Cheers</p>
