Access text in dynamic script with Ember using Protractor

How can I access the text "All changes saved" in the dynamically created Ember script below? I use Protractor to create functional test.

<div class="is-muted">
      <script id="metamorph-191-start" type="text/x-placeholder"></script>
      <script id="metamorph-191-start" type="text/x-placeholder"></script> 
      All changes saved 
      <script id="metamorph-191-end" type="text/x-placeholder"></script>
</div>

Thank you in advance for your help!
