You should think about what you're asking here. Jinja2 is a server-side technology, and the template is rendered before it gets sent to the browser. Your Ajax function runs on the client side, after the list variable has been turned into HTML. There is no way to do what you're asking.

Either get your Ajax function to return rendered HTML rather than JSON (ie render the Jinja template in the Ajax server-side handler) or use a client-side template technology - the author of Jinja2, Armin Ronacher, has also written JsonJinja which might do what you want.
