title: Set active class on ng-click in ui-router
body: <p>Here's the repo of my project: <a href="https://github.com/vipul-verma/naysa" rel="nofollow">https://github.com/vipul-verma/naysa</a></p>
  
  <p><strong>Problem:</strong></p>
  
  <p>In navigation.html I have added a controller named navCtrl and also I added activemenu function to set active class on clicked li tag, but when I load the page first active class is applied to li 'about' as it was set at starting point. </p>
  
  <p>But when I click another li tag it first adds a class to currently li tag but then refresh it and adds it back to 'about' li tag.</p>
  
  <p>Please help to make the active class on clicked element.</p>
