Fine Uploader file ID is always 0, how to change it? - fine-uploader

Question

I am using Fine Uploader's feature "initial file list". After some initial troubles I am now able to display my files and want to handle the deletion of uploaded items.
According to http://docs.fineuploader.com/branch/master/features/session.html my server-side should provide a JSON array with Objects containing at least name and uuid (I am using the Simple mode of Fine Uploader).
As you can see from the log below, the UUID property is handled without problems, I am receiving it on the server side and deleting the file successfully.
The problem comes from the fact that after a successful deletion I want to do something else on the client side and that is why I listed to the deleteComplete event like this:
.on('deleteComplete', function (event, id, xhr, isError) {
if (!isError) {
console.log("reducing the uploaded items");
.... // do something here
}
Now the id parameter is 0 which is a blocker for me because I have to use it for further processing. I guess the 0 comes from the submitted delete request before.
So what I am looking for is a way to somehow tell Fine Uploader what my id is. I guess if I am able to do it correctly when filling the initial file list then it will be correctly propagated to the deleteComplete method.
Output from Fine Uploader when I load the page with an initial file list and delete one of the files afterwards:
...
"[Fine Uploader 5.1.3] Attempting to update thumbnail based on server response."
"[Fine Uploader 5.1.3] Detected valid file button click event on file '7a5a2ebd-f7d3-40a1-b9da-cde5fc9307c6', ID: 0."
"[Fine Uploader 5.1.3] Submitting delete file request for 0"
"[Fine Uploader 5.1.3] Sending DELETE request for 0"
"[Fine Uploader 5.1.3] Delete request for '7a5a2ebd-f7d3-40a1-b9da-cde5fc9307c6' has succeeded."
....

As seen in the comments, it turned out that the id field is something that Fine Uploader manages internally and manipulating this is not possible and not wanted. As all of my items have their own uuid field I was able to use that one for further processing and distinguishing between the deleted files.
In order to retrieve the uuid field for a provided id one can use the get uuid from an id method which goes like this:
var uuid = $('#fine-uploader').fineUploader('getUuid', id);
