title: AngularJS ng-controller not working
body: <p>I just now started learning on AngularJS from <a href="http://www.w3schools.com/angular/angular_intro.asp" rel="noreferrer">w3schools</a>. I am trying to practice examples what ever they have mentioned in the tutorials. Every thing works fine but when i came to "AngularJS Controllers" it is not working properly as working well in <a href="http://www.w3schools.com/angular/tryit.asp?filename=try_ng_intro_controller" rel="noreferrer">w3schools Try it Yourself »</a>. I ve forked my code into this <a href="http://jsfiddle.net/santosh_patnala/dq8r196v/1/" rel="noreferrer">fiddle example</a>.
  My script looks like this:</p>
  
  <pre><code>function personController($scope) {
      $scope.firstName= "John";
      $scope.lastName= "Doe";
  }
  </code></pre>
  
  <p>Try to help me out and suggest me a good tutorial(or any free pdf file).</p>
