observe_field generates the JS to produce an XMLHttp request to the controller / method you specify in the :url parameter. I'm not sure I understand exactly what you mean when you say "call a REST-path" but the browser will expect a JS response. If you'll say more about exactly what you're trying to accomplish, perhaps we can be of more assistance.
