Run a script when Button/Link is clicked

I need to run a tracking script if a specific Link/Button is clicked. So far I got this:

<script>
document.addEventListener("DOMContentLoaded", function(event) {
jQuery('#termin').click(function(){ 
<script type="text/javascript" src="https://adfarm1.adition.com/track?tid=XXXXX&sid=XXXXX&type=js&orderid=&itemno=&descr=&quantity=&price=0.00&total=0.00&gdpr=${GDPR}&gdpr_consent=${GDPR_CONSENT_39}"></script>
}); </script>
