Answer 1

You could have

Markup

<a ng-click="toggleList()">
     View More <span class="glyphicon" ng-class="getClass()"></span>
</a>

Code

$scope.toggleList = function(){
   //other logic here
   $scope.isDown = !$scope.isDown; 
}

$scope.getClass = function(){
    return $scope.isDown ? 'glyphicon-chevron-down': 'glyphicon-chevron-up';
}
