title: inline editing in angularjs save item
body: <p>I try to avoid any directive as I want to learn more, but I can't get it working <strong>on the save part</strong>. </p>
  
  <p>partially working code here : <a href="http://jsfiddle.net/U3pVM/3789/" rel="nofollow">http://jsfiddle.net/U3pVM/3789/</a></p>
  
  <p>is it good to avoid using <code>$index</code>? because I use a lots of <code>this</code> </p>
  
  <pre><code>$scope.saveEditedTask = function(i){
      this.editable = false;  
  }
  </code></pre>
