title: Binding variables from Service/Factory to Controllers
body: <p>I have a variable that will be used by one or more Controllers, changed by Services.
  In that case, I've built a service that keeps this variable in memory, and share between the controllers.</p>
  
  <p>The problem is: Every time that the variable changes, the variables in the controllers aren't updated in real time. </p>
  
  <p>I create this Fiddle to help. <a href="http://jsfiddle.net/ncyVK/">http://jsfiddle.net/ncyVK/</a></p>
  
  <p>--- Note that the <code>{{countService}}</code> or <code>{{countFactory}}</code> is never updated when I increment the value of count.</p>
  
  <p>How can I bind the Service/Factory variable to $scope.variable in the Controller? What I'm doing wrong?</p>
