Jason,
ColdFusion cannot be directly invoked from JavaScript without a interface to
call a service.
ColdFusion is processed and then the end result is passed through the web
server to your browser. At that point essentially, the page is static.
If you want interactivity, you have to call another page or service to
activate CF enabled templates. This is typically done in AJAX when using
JavaScript. You can do this also in Flash with Flex.
