AngularJS factory undefined error - angularjs

Question

I am stuck here, I don't know what I am missing or how to debug this further. I continue to get this error: 'updateMemberServiceFactory is undefined' when I call it from an ng-click event. Please advise. If this is a simple typo I apologize I just can't see what's wrong. I'm trying to call into a PUT method on my controller but it never gets called. New to AngularJS. Thank you.
securityApp.factory('updateMemberServiceFactory', function ($http) {
function update(memberServiceID) {
$http({ method: 'PUT', url: 'http://localhost:62791/api/MemberServices/', data: { memberServiceID: memberServiceID } })
.then(function (result) {
alert('success');
}, function (errorResponse) {
});
};
});
securityApp.controller('memberServicesController', function ($scope, $http, $routeParams, $location, getTokenFromServer, updateMemberServiceFactory) {
var id = $routeParams.memberID;
$scope.username = 'aharris1#test.com';
$scope.password = 'SuperPass1!';
getTokenFromServer.getToken($scope.username, $scope.password).then(function (data) {
$scope.token = data;
$http({ method: 'GET', url: '/api/MemberServices/' + id + '?access_token=' + $scope.token, headers: { 'Authorization': 'Bearer ' + $scope.token } })
.success(function (response) {
$scope.memberServices = "";
$scope.memberServices = response;
$http({ method: 'GET', url: '/api/Members/' + id + '?access_token=' + $scope.token, headers: { 'Authorization': 'Bearer ' + $scope.token } })
.success(function (response) {
$scope.member = response;
});
$http.get('/api/ServiceTypes/')
.then(function (response) {
$scope.serviceTypes = response.data;
});
});
});
$scope.updateMemberService = function () {
updateMemberServiceFactory.update( { memberServiceID: memberServiceID }, null, function () {
alert('update called');
});
};
});

When you use someApp.factory(someFunction) the some someFunction should return an object that will be injected when needed.
In your case:
securityApp.factory('updateMemberServiceFactory', function ($http) {
function update(memberServiceID) {
$http({ method: 'PUT', url: 'http://localhost:62791/api/MemberServices/', data: { memberServiceID: memberServiceID } })
.then(function (result) {
alert('success');
}, function (errorResponse) {
});
};
return { // <---- this object will get injected, when required
update : update
}
});
