ajax call does not allow alphanumeric parameters in data

ajax call does not allow alphanumeric parameters in data

Hello all,

JQuery seems to be giving an error when trying to pass an alphanumeric parameter like so:

            $.ajax({
                type: "POST",
                url: "Default.aspx/AjaxTest",
                data: "{eventID:9a5}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function(msg) {
                    alert(msg.d);
                },
                error: function(e) {
                    alert("Event could not be added to calendar");
                }
            });

when the above method is called, the error callback is called. However when I change the eventID parameter to a purely numeric value, it works fine and the success callback is called. I would like to pass an alphanumeric value to a server method and this doesnt seem to work. Any help would be appreciated.
