title: Bind string to checkbox value in AngularJS
body: <p>I've been browsing for a few hours, found similar examples, however, couldn't make it to work.</p>
  
  <p>In my JSON file I've got property "accessRight" which could be "full", "read" or "none"
  Then in HTML I've got 3 checkboxes for "full" "read" and "none".
  If "accessRight" is set to "read", I want this checkbox to be checked and got this code to do it.</p>
  
  <pre><code>                &lt;input type="checkbox" data-ng-model="accessRight" data-ng-true-value="read"&gt; 
  </code></pre>
  
  <p>However the checkbox get checked even if "accessRight" isn't set to "read", how could I fix it?</p>
  
  <p>Also tried this but still no luck.</p>
  
  <pre><code>                &lt;input type="checkbox" data-ng-model="accessRight" data-ng-true-value="read"&gt; 
  </code></pre>
