Pseudo Code:-

    app.controller('myController', ['$scope', '$location','$http', 'ItemListService'

                    function($scope, $location, $http, ItemListService){

       $scope.data = function(){

       ItemListService.getAllItems(); //get all the items;

    };

        $scope.saveMethod = function(item){

       $scope.data = ItemListService.save(item); //this is the refresh part, return data through save method. Pull the latest data and bind it to the scope.

         $location.path('/fooView'); //dont think you even need this if you are entering data in a modal sorta thing, which on the same view. 

    }

    }]);

You service should look like,

app.service('ItemListService', function(){

    this.getAllItems = function(){

      //get the items from itemList

     //return all the items

   }



  this.save = function(item){

     //save the item in itemList

     //**return all items again, call getAllItems here too.

}

});

Hope this helps!!
