AngularJS $http custom headers not working - angularjs

Question

I'm trying to add a custom header to an HTTP request but AngularJS does not seem to handle it. Here is my code:
$http({
method: "GET",
url: 'http://localhost:8080/Schedule-service/login',
headers: {
'X-AUTHENTICATION': 'TRUE'
}
}).success(function (response) {
$cookies[constants.TOKEN] = response.hash;
}).error(function (data, status, headers, config) {
});
I have tried to add this to the default headers but still nothing. What is wrong here?
Edit:
My request in the middle of doing GET:
Request URL:http://localhost:8080/Schedule-service/login
Request Headers CAUTION: Provisional headers are shown.
Access-Control-Request-Headers:accept, x-authentication
Access-Control-Request-Method:GET

And after GET:

Request Method:OPTIONS

It seems you're performing CORS request and the request you pasted is preflight request. The application is working on port 80 but you're calling service on port 8080 hence its CORS cross origin. In the response above you see that the server will accept x-requested-with header
Access-Control-Allow-Headers:origin, content-type, accept, x-requested-with.
The header should be visible in the next request
