ajaxFileUpload onchang上传文件插件第二次失效刷新一次才能再次调用触发change事件

关于用ajaxfileupload时，遇到一个要刷新一次页面才能再次上传,

ajaxFileUpload 用onchang上传只能上传一次 第二次就失效了 我找这个问题找了很长时间

ajaxFileUpload = (fileElementId) => {
            var jq: any = $;
            var that = this;
            var d: any = $(this);
            d.jqLoading();
            jq.ajaxFileUpload
                (
                {
                    url: BatchInvoiceUrls.UploadExcelUrl, //用于文件上传的服务器端请求地址
                    secureuri: false, //是否需要安全协议，一般设置为false
                    fileElementId: fileElementId, //文件上传域的ID
                    dataType: 'text', //返回值类型 一般设置为json
                    type: "post",
                    //contentType: 'text/html;charset=UTF-8',
                    //ContentType:'text/html;charset=UTF-8',
                    success: function (data, status)  //服务器成功响应处理函数
                    {
                           //这里是成功处理
                            $.fn.jqLoading("destroy");

                    },
                    error: function (data, status, e)//服务器响应失败处理函数
                    {
                        alert(e);
                    }
                }
            )
            $("#fileExcel").replaceWith('<input class="file" type="file" id="fileExcel" name="fileExcel" accept="application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" onchange="module.ajaxFileUpload(\'' + fileElementId+'\')" />');
            return false;
        }

onchange需要重新绑定
