bootstrap-fileinput4.4设置为同步上传后不走回调

Question

当uploadsync：true时正常回调，然后换成false后，就不再走回调了，不知有办法解决么？

调用代码：

    var sinput= $("#input-ficons-3").fileinput({
                uploadUrl: basePath+"/prizes/addFile.do",
                language: 'zh',
                uploadAsync:false,
                maxFileCount:5,
                uploadExtraData:function () {
                    return {
                        ftype:2
                    }
                },
                previewFileIcon: '<i class="fa fa-file"></i>',
                allowedPreviewTypes: ['image', 'text'], // allow only preview of image & text files
                previewFileIconSettings: {
                    'docx': '<i class="fa fa-file-word-o text-primary"></i>',
                    'xlsx': '<i class="fa fa-file-excel-o text-success"></i>',
                    'pptx': '<i class="fa fa-file-powerpoint-o text-danger"></i>',
                    'pdf': '<i class="fa fa-file-pdf-o text-danger"></i>',
                    'zip': '<i class="fa fa-file-archive-o text-muted"></i>',
                }
            }).on('filepreupload', function(event, data, previewId, index) {
                console.log('File uploaded params2222666666',data);
            }).on('fileuploaded', function(event, data, previewId, index) {
              console.log('File uploaded params',data);
            });

        找到答案了。。同步时需要用 “filebatchuploadsuccess”接收成功回调。。
