Jquery dropzone中的进度条不工作

我正在尝试向dropzone.js添加进度条。当我添加文件时，会出现进度条，但当我按下保存按钮时，什么也没有发生。“保存”按钮是保存文件的自定义按钮，这些文件已添加到dropezone中。我就是这样做的

$(document).on("click", "#AddLogoForm .btn-save", function (e) {
    e.preventDefault();
    e.stopPropagation();
    if (logoDropzone.files.length > 0)
    {
        logoDropzone.processQueue();
    }
    else
    {
        $("#AddLogoForm").submit();
    }
    logoDropzone.on("success", function() {
        location.reload(true);
    });
});

这是我添加进度条的HTML代码

<div class="progress progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0">
<div class="progress-bar progress-bar-success" style="width:0%;" data-dz-uploadprogress></div>
</div>

function DropzoneInit() {
var previewNode = $("#template");
previewNode[0].id = "";
var previewTemplate = previewNode.parent().html();
previewNode.remove();

var logoDropzone = new Dropzone("#AddLogoForm", {
    url: $("#AddLogoForm").attr("action"),
    thumbnailWidth: 80,
    thumbnailHeight: 80,
    maxFiles: 1,
    autoProcessQueue: false,
    previewTemplate: previewTemplate,
    previewsContainer: "#logopreviews",
    clickable: "#AddLogoForm .dz-input",
    accept: function (file, done) {
        if (file.type != "image/jpeg" && file.type != "image/png" && file.type != "image/gif") {
            done("Error! Files of this type are not accepted");
        }
        else { done(); }
    }
});
