An array of objects can not be seen in the method. (angularjs)

Sorry for my english.

chill.controller('messagesController', function($scope, $http, $rootScope, $location, $stateParams, $ionicSlideBoxDelegate, $ionicLoading) {

if ($rootScope.userData != undefined) {
    $ionicLoading.show({
        template: 'loading'
    })
    $http.get('http://ift.tt/1HlXCMj'+$rootScope.userData.id_user+'/id_contact/'+$stateParams.id)
    .success(function(data) {
        $scope.messages = data;
        for (var i = 0; i < $scope.messages.response.length; ++i) {
            if ($scope.messages.response[i].type == 'location') {
                var strings = $scope.messages.response[i].content.split(' ');
                var lat1 = strings[0], lat2 = strings[1];
                $http.get('http://ift.tt/WJEHSa'+lat1+','+lat2+'&sensor=false')
                .success(function(data) {
                    $ionicLoading.hide();
                    $scope.messages.response[i].address = data.results[0].formatted_address;
                });
            };
        };
        $ionicSlideBoxDelegate.update();
    });
}
else
{
    $location.path('/login');
};

});

An array of objects $scope.messages.response[i].address not visible(undefined) in success(function(data){}.

Help me, please.
