想问一下关于bootstrap fileinput图片上传的问题！

是这样 我想知道图片回显过来之后，删除完图片 怎么回调下函数

$(function() {

                var obj = parent.document.getElementById("iframepage"); //取得父页面IFrame对象 

                obj.height = parent.document.body.scrollHeight - $(document).height(); //调整父页面中IFrame的高度为此页面的高度 



                var imgUrl = $('#imgUrlEdit').val();

                if(imgUrl != "null"){

                    $("#fileEdit").fileinput('refresh', {

                        initialPreview: "<img class='file-preview-image' alt='Desert' title='Desert' src='<%=todayPriceAfter.getImgUrl()%>'/>",

                        initialPreviewConfig: [{

                            caption: 'desert.jpg',

                            width: '120px',

                            url: root + '/todayPriceAfter/imgDelete?imgUrl=' + imgUrl,

                            key: 100,

                            extra: {

                                id: 100

                            },

                        }],

                        showRemove: true,

                        initialPreviewShowDelete: true,

                        initialPreviewThumbTags: [{

                            '{CUSTOM_TAG_NEW}': ' ',    

                            '{CUSTOM_TAG_INIT}': 'lt;spanclass=\'custom-css\'>CUSTOM MARKUP;/span>'

                        }],

                        removeFromPreviewOnError: true

                    });

                }

                $("#fileEdit").on("fileuploaded", function (event, data, previewId, index) {

                    var datas = eval(data);

                    $("#imgUrlEdit").val(datas.response.shu);

                });

            });
