Why Unable to get success callback in Jquery/ajax call to RESTful services?

function GET() {
        jQuery.support.cors = true;
        $.ajax({
            url: 'http://localhost:32253/api/UserDetail/GetRoleDetails',
            type: 'GET',
            async:true,
            contentType: "application/json",
            dataType: 'json',
            xhrFields: {
                withCredentials: true
            },
            error: function (xhr, status)
            {
                alert(status);
            },
            success: function (data) {
                alert("Success!");
            }

        });
        return false;
    }

I am very much new to ajax,I tried a ajax call to my services method which returns value.But the success callback function is never fired .I only get error.What might be the reason? I tried using dataType to jsonp and other similar solutions which had been found in Stackoverflow regarding this issue.Nothing worked out.I am getting server response as 200 oK.

        beforeSend: function (xhr) {
        },
        error: function (request, status, error) {
            console.log("Error In Web Service...." + request.responseText);
            return false;
        },
