AngularJS View Not Updating Using Defer and Factory - angularjs

Question

I am currently having an issue where when I try to create a new setting my view is not being updated until I refresh the page. Can anyone point me into the right direction? If I am going about this the wrong way please let me know a better way to do this.
app.factory('SettingsFactory', function ($http, $q) {
//$scope.settingData = {}
return {
getAllOptionsAsync: function(callback) {
var deferred = $q.defer();
$http.get('/api/settings').success(callback);
},
deleteOptionAsync: function(id) {
//console.log('reached');
var deferred = $q.defer();
$http.delete('/api/settings/' + id);
},
createOptionAsync: function(settingData) {
var deferred = $q.defer();
$http.post('/api/settings', settingData).success(function(data) { console.log(data);
deferred.resolve(data);
// console.log(deferred.promise);
return deferred.promise;
});
}
};
});
var controllers = {};
controllers.SettingsController = function($scope, SettingsFactory) {
//$scope.settings = SettingService.list();
SettingsFactory.getAllOptionsAsync(function(results) {
//console.log(results);
$scope.settings = results;
});
$scope.create = function() {
// console.log('called');
// console.log($scope.formData);
SettingsFactory.createOptionAsync($scope.formData).then(function(data) {
console.log(data);
$scope.settings = data;
});
}
$scope.delete = function(id) {
//console.log(id.entity._id);
SettingsFactory.deleteOptionAsync(id.entity._id);
}
$scope.gridOptions = {
data: 'settings',
multiSelect: false,
columnDefs: [
{field: 'option'},
{field: 'value'},
{displayName: 'Edit', cellTemplate: '<button id="editBtn" type="button" class="btn btn-primary" ng-click="open(settings._id)" >Edit</button> <button id="deleteBtn" type="button" class="btn btn-primary" ng-click="delete(row)" >Edit</button> '}
]
};
}

Inside of the then or anytime you are updating the scope in a callback you need to wrap the $scope.settings=data with a scope.apply.
$scope.$apply(function() {
$scope.settings=data;
});
