When creating a Quote PDF i want to react to this event by custom logic in a Salesforce Apex Trigger.

I created a trigger for it:

trigger QUOTEDOCTRIGGER on ContentVersion (after insert) {
    for (SObject cv : Trigger.new) {
        System.debug('********************************************' + String.valueOf(cv.Id) + '*************************************************');
    }
}

The created trigger isn’t trigger and doesn’t show up in the log.

Is this wanted behavior or a bug?
