You could set up a global ajax handler as described here:
http://api.jquery.com/ajaxsuccess/
You'd do this from custom JS in a page load rule. Inside the handler, you'll need to inspect to make sure that you got the success event from the ajax call that you care about. I simple if / then should do the trick. Then you could call _satellite.track to trigger a DTM rule with the tracking that you want to send to AA.
Start with something like this:
$( document ).ajaxSuccess(function( event, xhr, settings ) {
console.log("ajaxSuccess!!!",event, xhr, settings);
if ( settings.url == "ajax/test.html" ) { //modify this to match your specific ajax call.
console.log( "Triggered ajaxSuccess handler. The Ajax response was: " + xhr.responseText );
//This shows how to set a dynamic data element that you can use in the AA portion of your direct call rule (like this %l_myAjaxResponse%)
_satellite.setVar("l_myAjaxResponse", xhr.responseText);
//This triggers your direct call rule
_satellite.track("myAjaxTracking");
}
});
