What version of Rails are you using? It looks like remote_function was depracated in 3.1 http://apidock.com/rails/ActionView/Helpers/PrototypeHelper/remote_function

Use jQuery to respond to the change event:

jQuery ->
  $("#select_id").change ->
    $.ajax(
      url: "url",
      dataType: "json",
      data: "data to send")
        .done (data) ->
          do_something_on_success()
        .fail (data) ->
          do_something_on_fail()
