title: First steps with ionic to get popup alert on button tap / click
body: <p>I am trying to understand the concept how ionic framework works and how to use the controllers.
  More specifically, I am trying to add a button that would display a alert / popup to the slidebar example with some code from the documentation. 
  Unfortunately no 
  success. I am not sure how to debug the app because the ionic server is not consistent with the simulator. 
  Is there a good tutorial (not the official page) out there? What is the best way to dig into it? I am moving to slow for my taste. I am familiar with ios coding by the way, and I sort of miss the comfortable ios environment...</p>
  
  <p>Here's the code I wrote for the button alert click:
  in one of the html files</p>
  
  <pre><code>&lt;button ng-click="showPopup()" class="button icon ion-edit"&gt;&lt;/button&gt;
  </code></pre>
  
  <p>in controllers.js</p>
  
  <pre><code>.controller('PlaylistsCtrl',function($scope, $ionicPopup, $timeout) {
  
  // Triggered on a button click, or some other target
  $scope.showPopup = function() {
    $scope.data = {}
  
      // An alert dialog
      $scope.showAlert = function() {
          var alertPopup = $ionicPopup.alert({
              title: 'Don\'t eat that!',
              template: 'It might taste good'
          });
          alertPopup.then(function(res) {
              console.log('Thank you for not eating my delicious ice cream cone');
          });
      };
  };
  });
  </code></pre>
  
  <p>Fixed
  Thanks for the input. I'll try to fix it. I realized that it's not ionic but angularjs that I have to read upon, for which I now found a good book.Thanks</p>
