It's not AJAX if you're hard-coding all the entries into the template,
it's just basic Javascript, but never mind.
You don't show how you're rendering that template, but I suspect that
you're not using RequestContext.
Bear in mind that the context processor is run for *every single view*
(again, as long as you use RequestContext), which may not be what you
want. I'd suggest a template tag for this use case. Or you could
actually make it Ajax, so it requests matching entries dynamically.
