use factory/service store goals responsible sharing data among controllers.

myapp.factory('myservice', [function() {         var goals = {};         return {             getgoals: function() {                 return goals             },              setgoals: function(op) {                 goals = op;             },         }     }])     .controller('nlgoalsctrl', [function($scope, myservice) {         $scope.goals_selected  = {};         //update goals_selected         myservice.setgoals($scope.goals_selected );     }])     .controller('nlsessionsctrl', [function($scope, myservice) {         //fetch         $scope.goals_selected  = myservice.getgoals();     }]);
