Track number of downloads in social sharing plugin


I would like to track the number of times a file is downloaded from the URL specified, but I cannot get it to work.

It would be great if you could add an id to the download-link so it would be possible to track clicks on the link. As you can see from this screenshot, there is no id right now:

And preferable the ID would include the id of the ad to make it unique (eg. wdsm_ad-474-download) just like the container has a unique id: wdsm_ad-474-container.
