hi I am adding existing images to dropzone. my custom binding code is:

ko.bindingHandlers.dropzone = {
            init: function (element, valueAccessor) {
                var value = ko.unwrap(valueAccessor());

                var options = {
                    maxFileSize: 15,
                    uploadMultiple: true,
                    parallelUploads: 100,
                    maxFiles: 30,
                    addRemoveLinks: true,
                    acceptedFiles: ".jpeg,.jpg,.png,.gif",
                    init: function () {
                        var myDropzone = this;
                        this.on("success", function (file, serverFileName) {
                            fileList = [];
                            i = 1;
                            var abc = $.map(serverFileName, function (item) { return (item); });
                            $.each(abc, function (index, value) {
                                fileList[i] = { "fileName": value, "fileId": i++ };
                            })
                        });
                        if (images) {  //here
                            for (i = 0; i < images.length; i++) {
                                myDropzone.emit("addedfile", images[i]);
                                myDropzone.emit("thumbnail", images[i], "/Images/Ads/");
                                myDropzone.emit("complete", images[i]);
                            }
                        }
                    }
                };

                $.extend(options, value);

                $(element).addClass('dropzone');
                new Dropzone(element, options); 
            }
        };

I am fetching existing images data through ajax but the above code is executed before ajax response is received and existing images are not shown. How can I handle this?
