jQuery FileUpload doesn't trigger 'done'

Question

I use jQuery-File-Upload plugin. I wrote a simple code to test it - and it works, but not without problems. It doesn't trigger done, even if the file is uploaded and progress bar reached its end.

Here's the code:

$('#file_file').fileupload({
    dataType: 'json',
    autoUpload: true,
    add: function (e, data) {
        data.context = $('<p/>').text('Uploading...').appendTo(document.body);
        data.submit();
    },
    progressall: function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('#progress .bar').css(
            'width',
            progress + '%'
        );
    },
    done: function (e, data) {
        alert('Done');
    }
});

My input is as simple as that:

<input type="file" id="file_file" name="file[file]" />

If your server is not returning JSON, try removing:

dataType: 'json'

Otherwise you may be ending up with a fail event, which is easy to test for:

fail: function(e, data) {
  alert('Fail!');
}

I changed couple of things and it works. Here:

$('#file_file').fileupload({
    autoUpload: true,
    add: function (e, data) {
        $('body').append('<p class="upl">Uploading...</p>')
        data.submit();
    },
    progressall: function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('#progress .bar').css(
            'width',
            progress + '%'
        );
    },
    done: function (e, data) {
        $('.upl').remove();
        $.each(data.files, function (index, file) {
            /**/
        });
    }
});

I repaired with autoUpload: true, it looks like when the autoUpload property is not set (even if upload is working as expected) the done event is not triggered.
