title: Revert ng-model value in Angular JS
body: <p>Is it possible to revert the model value when displaying it?</p>
  
  <p>My controller has this property:</p>
  
  <pre><code>this.config = {client: false, name: true};
  </code></pre>
  
  <p>And I want to use the values like this:</p>
  
  <pre><code>&lt;label&gt;
    &lt;input ng-model="ctrl.config.client"&gt; Client
  &lt;/label&gt;
  
  &lt;div ng-hide="ctrl.config.client"&gt;Client&lt;/div&gt;
  </code></pre>
  
  <p>I'd like to show the input checked when the config.client value is false. How can I do it?</p>
