angularjs - Recall function from function -

i have function, loads json file , populates scope. if fails, loads ionicpopup 2 choices, ok , retry. i'd relaunch function on retry

here's code

$scope.loadevents = function () {  $http.get('https://api.paris.fr/api/data/1.4/quefaire/get_activities/?token=[foobar]&cid=3,9,18,20,16,10,4,37,1,29,30,11,42,25,5,33,8,39,6,40,17,38,34,32,2,44,23&tag=6,4,7,44,2,45,48&created=0&start=0&end=0&offset=1&limit=50',{header : {'content-type' : 'application/json; charset=utf-8'}}) .success(function (data) {   $ionicloading.hide();   $scope.products = data.data;   var randomproduct = math.round(math.random() * ($scope.products.length - 1))   $scope.currentproduct = angular.copy($scope.products[randomproduct]);   $scope.currentproduct.image = $scope.checkhttp(); }) .error(function (data, status, headers, config) {   $ionicloading.hide();   $scope.errormessage = "couldn't load list of events, error # " + status;   var alertpopup = $ionicpopup.confirm({     title: 'could not load list of events, error #0',     template: '',     buttons: [       {text: 'ok'},       {         text: '<b>retry</b>',         type: 'button-positive',         ontap: function(e) {             console.log("reessayer");              //retry loadevents()              return false;         }}]       });                 console.log($scope.errormessage);     });   }   $scope.loadevents(); 

i dit this: if user clicks on ok returns true, , false if clicks on retry

then alertpopup checks promise , acts consequently

.error(function (data, status, headers, config) {   $ionicloading.hide();   $scope.errormessage = "couldn't load list of events, error # " + status;   var alertpopup = $ionicpopup.confirm({     title: $scope.errormessage,     template: '',     buttons: [       {text: 'ok',       ontap: function(e) {           return true;         }       },       {         text: '<b>retry</b>',         type: 'button-positive',         ontap: function(e) {             console.log("reessayer");              return false;         }}]       });       alertpopup.then(function(res) {           if(!res)             $scope.loadevents();           else {             console.log("stop");           }         });                 console.log($scope.errormessage);     });    }   $scope.loadevents();
