title: angularjs - ng-switch does not bind ng-model
body: <p>I have this repro <a href="http://embed.plnkr.co/nVCmukG5abpi1Y4ZHkrq">http://embed.plnkr.co/nVCmukG5abpi1Y4ZHkrq</a> that show when I click 'Title3' and enter a value in text box although the entered value shows reflected in the UI, when I click the 'click' button nothing is binded for the scope attribute $scope.test.</p>
  
  <p>I don't know what is wrong with ng-switch or maybe I'm doing something wrong. Help is appreciated!!!</p>
