title: How to set ng-disabled to false on specific button
body: <p>I have a fieldset that sets ng-disabled to true or false based on certain conditions.  </p>
  
  <pre><code>&lt;fieldset class="panel-body" ng-disabled="CoreFormPartVI.overview.UserReadOnly     || CoreFormPartVI.overview.Locked"&gt;
  </code></pre>
  
  <p>I have a button that I want to be enabled regardless of this fieldset. </p>
  
  <pre><code>excel-definition="CoreFormPartVI.PartVIRelationshipDefinition" ng-disabled="readOnly"
                              &gt;&lt;/div&gt;
  </code></pre>
  
  <p>I tried setting ng-disabled="false" on the button, but that doesn't seem to work.  Is there a way to say, disable everything except that specific button?</p>
