Syndicated Conditional Chat link and Engagement Engine

Content

I am setting up the Syndicated Conditional Chat link and Engagement Engine.  I told our web developer to add the below div structure where the link is to be positioned.  He tells me "This div node will not be present on page load as it's an ajax call that comes in after the page is loaded.  Basically, the div is injected into the dom as ajax call response."

I'm not a developer, but does anyone know if this would work this way?  So far no success.  My test rule works fine so I know the Engagement Engine is working and the javascript code is accurate.
