Send formData with Jquery Datatables ajax

So I'm using Jquery Datatables plugin in my project, I need to send formData and process it as my datatables source, however I have no idea how to get it working by using built in datatables ajax call. Here's my code :

$('#fDataSales').on('change', function () {
    var formData = new FormData($('#frmDataSalesUpload')[0]);

    $('#tblPreviewDataSales').DataTable({
        ajax: {
            url: '/DataSales/UploadPreview/',
            type: 'POST',
            data: formData
        }
    });
});

My MVC Controller :

public void UploadPreview()
{
     if (Request.Files.Count > 0) //always 0
     {
          //do something
     }
}
