Importing from dynamic content

I am building a site displaying search results from a metasearch and tried to support Zotero by adding a CoinS span for each search result.

The results are inserted into the page dynamically, rather than all being sent with the static page. And, it seems, that as a consequence of that Zotero (in Firefox 5) doesn't see that information and does not expose the handy import button to the user.

Is there any way I can tell Zotero that it should check the DOM for new data?
