Updating the dropkick. about dropkick

[vicky8987]

i have the same issue with latest "jquery.dropkick.js". I was using your old dropkick.js. now it's stopped working for IE11. e.g: http://www.intellichoice.com/certified-pre-owned.html . Refer cpohome.js, I searched but found that everyone is saying to updated dropkick version.
But with updated one I'm stuck. I'm not able to update dropkick value in an ajax call.
code bellow:
success: function(response) {
optionData = "";
optionData += "Model";

                    var json = jQuery.parseJSON(response);
                    $.each(json, function() {
                        var modelId = this.VehicleModelId;
                        var model = this.VehicleModel;
                        optionData += "<option value='" + modelId + "'>" + model + "</option>";
                    });
                    alert(optionData);
                    $select = $("#ddlModel_2");
                    $select.removeData("dropkick");
                    $("#dk_container_ddlModel_2").remove();
                    $select.html(optionData);
                    optionData = '';
                    $("#ddlModel_2").dropkick({
                        change: function(value, label) {
                            $('#VehicleModel').val(label);
                            $('#vehicle.model').val(value);
                        }
                    });

                }

---

from above code due to line "$("#dk_container_ddlModel_2").remove();" my dropdown is getting removed, but if I'm continue with the line I'm getting two dropdowns, first one with old value and second with new Ajax value.
Please suggest what to do, should i use old version then let me know solutions for IE11 or should i use old one, then tell me solutions for getting 2 times dropdowns.
Thanks.
