How to add 3rd party click trackers in DCM implementation

[vai...@zapr.in]

Hello All,

We usually get DCM trackers to be added while serving media content. (Refer to following sample code snippets). However, I am facing issue in adding a 3rd party click tracker as well over the media content.

<ins class='dcmads'
style='display:inline-block;width:300px;height:250px'
data-dcm-placement='N7480.1664088DOUBLECLICK.NETTEST/B8299600.114131924'
data-dcm-rendering-mode='iframe'>
<script src='https://www.googletagservices.com/dcm/dcmads.js'></script>
</ins>

SInce, the sbove snippet will add IFRAME dynamically in DOM, I can not add a click event listener & fire the tracker. However, I found "data-dcm-click-tracker" as an attribute which could help me out here. 

But it is not working as expected. 

Can someone pls. help me with the usage purpose of this attribute and how to use it?

Also, if this tracker is not the resolution to my actual problem, what other things can I do?

I would really appreciate if someone could help me troubleshoot this implementation issue.
