The short answer is that the element (created by link_to_remote) that submitted the request to the server told the server via the message type (XMLHttpRequest) that the browser expected JS, not HTML, returned. Your first attempt used render which returned just the HTML you wanted displayed. Your second returned the HTML along with the JS to display it.
