Correct way to update scope value in angularjs view

View code

 <a ng-click="deleteOrdersUpdate()">Update</a>
 <span class="red">{{noOfOrders}}</span>

Controller code

 $scope.deleteOrdersUpdate=function () {
 $scope.noOfOrders=$scope.selection.length;
 scope.$apply();
 };

I keep getting $rootScope:inprog Action Already In Progress error.

What is the correct way to do this?Can any one please point me in the right direction.

There's no reason to call $apply here as you're already operating within the angular context.

$scope.deleteOrdersUpdate = function () {
     $scope.noOfOrders = $scope.selection.length;
 };

You have to check if it is already in any digest cycle, if it is then it will be automatically done, you don't need to do this, if not then you can apply the scope

if(!$scope.$$phase) {
    $scope.$apply();
}
