Google DFP on AJAX Site

I have an AJAX site that is using DFP to deliver Adsense Ads. I have been putting the Ads into iframes (iframes I created) and have been finding the clicks occur, profile shows and then it is reversed. (eg: the click disappears). I have done a fair amount of testing and I can see the problem is the iframes I have been putting the Ads into. When the iframe is removed the clicks remain and register in adsense. The JOB: I need someone experienced with DFP and AJAX to help guide me though the proper way to refresh DFP Ads on an AJAX Site. I've read a fair few website pages on this topic but I would like some experience to help assist and teach me. Basically all I'm after is: - I have around 8 Ad slots - when the page is clicked on (AJAX refreshes) and the AD needs to change. Note: I'm happy to pay $100US for this. thx
