title: Nativescript using custom icons on NavigationButton
body: <p>I'm trying to add a button with custom fonts on the ActionBar on a NativeScript Angular app. This is what I tried so far:</p>
  
  <pre><code>&lt;ActionBar class="cp-icon"&gt;
      &lt;NavigationButton text="&amp;#xE801;" (tap)="goBack()"&gt;&lt;/NavigationButton&gt;
      &lt;Image src="res://logo_h_white"&gt;&lt;/Image&gt;
  &lt;/ActionBar&gt;
  
  // Or one of these optio
  &lt;ActionItem text="&amp;#xE801;" (tap)="goBack()"&gt;&lt;/ActionItem&gt;
  &lt;Label text="&amp;#xE801;"&gt;&lt;/Label&gt;
  &lt;Button text="&amp;#xE801;"&gt;&lt;/Button&gt;
  </code></pre>
  
  <p>But none of them seems to be working. I do have the font instaled because I can use in the view. Also, if I just change the text attribute to be a string instead of an icon, it also doesn't show nothing.</p>
  
  <p>Is there a way to do this?</p>
