Spring & AngularJS : Undefined status for PUT method - angularjs

Question

i am returning a string on updation of a record and want to show the same string on UI(updated successfully)
Here is my code :
#RequestMapping(method = RequestMethod.PUT, value = "/update")
public #ResponseBody String update(#RequestParam("id") int id, #RequestParam("name") String name) {
employeeService.update(id, name);
return "updated successfully";
front end code :
$scope.update = function(Employee) {
$http({
method : 'PUT',
url : '/Employee/update',
params : {
id : Employee.id,
name : Employee.name
}
}).success(function(data, status, headers, config) {
$scope.updatedText = data;
$scope.updatedFlag = true;
}).error(function(data, status, headers, config) {
console.log("data.token " + data.token);
});
};
Here are two interesting screen shots
here status is undefined
again
here status is 200
please let me know what is the reason behind that and yes i can see that there is a change in the hibernate table
Please help

Well i'll leave you an example how i handle calls to the API with $http and promises $q
i use it inside a service, that can be injected on my controllers.
this.update = function (Employee) {
var datosRecu = null;
var deferred = $q.defer();
var token = $cookies.getObject('token');
$http({
url: '/Employee/update',
method: 'PUT',
params: {
id: Employee.id,
name: Employee.name
},
headers: {
'Authorization': 'Bearer ' + token,
'Content-type': 'application/json'
}
}).then(function successCallback(response) {
datosRecu = response;
deferred.resolve(datosRecu);
}, function errorCallback(response) {
datosRecu = response;
deferred.resolve(datosRecu);
});
return deferred.promise;
};
now when i inject it on my controller i can read the promise deferred.promise with all the data of response.
i hope it help you.
