Ember supporting XDomainRequest(xdr) for CORS

I am using ember 1.5 using grunt-cli and wanted to happen ajax call for CORS support using dataType: "JSON".

Ember.$.ajax({
    type: "GET",
    url: App.serverURL + 'logVisit', // callback for jsonP
    data : {
        'fp': App.fp
    },
    dataType : "JSON",
    success: function(response) {
        console.log('DEBUG: visitor has been registered');
    },
    error: function(jqXHR, textStatus, errorThrown) {
        var response = jqXHR.responseText;

        console.log('Failure!');
        if(jqXHR.status&&jqXHR.status==400){
            // alert(jqXHR.responseText);
            var response = $.parseJSON(jqXHR.responseText);

            if (response) {
                console.log(response.error);
            } else {
                // This would mean an invalid response from the server - maybe the site went down or whatever...
                console.log("DEBUG: Inside jqXHR.status : Something went wrong");
            }
        } else {
            console.log("DEBUG: Something went wrong");
        }
    }
});

on IE10/11 its running good but because of XDR, its not working properly and showing console as

LOG: Failure! 
LOG: DEBUG: Something went wrong

Any help or hack?
