angular scope update problem


I have the following code:

        restrict: 'A',
        link: function(scope,elem,attrs){
                if (elem.hasClass('alert alert-success')){
                    elem.removeClass('alert alert-success');

                }else {
                    elem.addClass('alert alert-success');
                        scope.carrito = parseFloat(scope.carrito) + parseFloat(elem.attr('precio'));
                        $localStorage.carrito = scope.carrito;





Open in new window

In the other page i have {{carrito}}, but it doesn't update until i refresh the page, any idea?

can you show your controller  please?
I'd first rewrite




Second the link function only adds an onClick handler to element, and that happens only once. But ths onClick function refers to scope. What scope? The scope of the element to which directive applies is defined by the ngModel/Controller for that element. If this is not in the correct context you might have to "require" the controller. Or you might do this another way. In any event I don't quite see what is being updated by the onClick. You might try testing this with Chrome (F12 key) to see if any strange errors regarding scope turn up.
