callbacks on fileNames are not triggered

The display_files-function of the MWE is not called after each upload.
It does work for the first time, but any successive call won't update the Output.

Files are uploaded to UPLOAD_FOLDER and the Complete Label is also changed.

Strangely it seems like no component prop is changed though.

Thanks for reporting the issue! If I understood correctly, the problem was in python, the fileNames is a list which will not "change" (the id is the same), if a string is appended into it. Therefore, I added another property isCompleted that is a boolean and tells when the upload is complete. The fileNames is still a list of strings. Maybe someday there will be a possibility for the user to select multiple files to be uploaded. Until then, the length of the fileNames will always be one.

I put the changes into the v.0.1.1 (commit 1ea6096) and updated the example in the README.md.

Hope it works for you now!
