File Upload with parameter


I tried to upload files.
Single files and multiple files are working without problem.

Now I would like to have a upload with a parameter.

There is something like this already in the upload controller:

I used upload/{id} as url in the file upload component.
But how is it possible to set the id?
The method does not fire if I upload a file.
