blueimp jquery-file-upload | Multiple instances and one global Upload-Button

[FunkeMT]

I'm using the bluimp jQuery-File-Upload-plugin (UI) to upload files in multiple instances.

I use one button which starts the upload process for every instance. 
Furthermore i have a global process statistic which summarized the stats from each instance.

    statsData = new Array(); // for global progress-bar/-stats
    $('.fileupload').each(function () {
        statsData.push($(this).fileupload({
        dropZone: $(this).closest('.dropzone'),
        url: 'foo/bar'
        }).bind('fileuploadadd', function (e, data) {
            $("#btn-submit-all").on('click', function () {
                $('.fileupload-progress.global.fade').show();
                data.submit();
        });
        }).bind('fileuploadstart', function (e) {
            $('.fileupload-progress.panel.fade', $(this)).show();
        }).bind('fileuploadprogress', function (e, data) {
            var progress = parseInt(data.loaded / data.total * 100, 10);
            $('.progress-bar', data.context).attr('value', progress);
        }).bind('fileuploadprogressall', function (e, data) {
            var progressall = parseInt(data.loaded / data.total * 100, 10);
            $('.fileupload-progress.panel .progress-bar', $(this)).attr('value', progressall);
            renderGlobalProgress(statsData);
        }).fileupload('progress'));
    });

So far, so good. 
The upload and the global progress-bar/-stats works fine.

The problem is now, when a file is `canceled` from the filelist, the file will be deleted from the list (upload template) but it is still in the "upload queue" (`filelist`?) and will upload.

I isolate the problem (probably?) to this part:

    // ...
    }).bind('fileuploadadd', function (e, data) {
        $("#btn-submit-all").on('click', function () {
            $('.fileupload-progress.global.fade').show();
            data.submit();
    });
    // ...

Because when i use the standard `Start Upload`-Button for each instance, everything works fine. 
But how can i use the global button to start the uploads instead of my resolution?
