How to overwrite upload function correctly and trigger all events like progress bar ?

[Dudy83]

Hi,

I would like to overwrite the upload function to send my files correctly with my back-end configuration. I know that I have to code my function in the "onChange" event but necessarily my code is not triggering all events like the progress bar or status message. And if i use "uploadOnDrop" event it will trigger the original function of dropzone-ui and not my function. How should i do ?

Thank you a lot for the help
