angularjs preflight request fails to load data

I am developing a single page application using Angularjs framework. inside my homeController i use a service call as below

 $http({
        method: 'POST',
        url: 'http://localhost:1530/api/Profile?username=sa&password=da',
        data: { Email: "dmytest@test.com", Password: "saas" },
        headers: {'Content-Type': 'application/json'}
    }).success();

The problem is that when i am making a api call the browser initiates a preflight request with method options instead of post. Server responds with all required headers.But the actual call is not done.Preflight request initiates only when using "Content-Type:application/json". I am posting Json data to server. Is there any way to either prevent the preflight request nor making a successfull api call?

It is working fine on mobile as well as on ajax call. Thanks in advance.
