angular.module('buttonsApp').directive('ladda', ['$timeout', function ($timeout) {
    return {
        restrict: 'A',
        scope: {
            stop: '=stop'
        },
        link: function postLink(scope, element, attrs) {
            var l = Ladda.create(element[0]);
            element.context.form.onsubmit = function(e) {
                l.start();
            };
            scope.$watch('stop', function(newVal) {
                if (angular.isDefined(newVal)) {
                    if (newVal) {
                        l.stop();
                    }
                }
            });
        }
    };
}]);
