coffeescript with jquery ajax

$.ajax '/',
    type: 'GET'
    dataType: 'html' error: (jqXHR, textStatus, errorThrown) ->
        $('body').append "AJAX Error: #{textStatus}"
    success: (data, textStatus, jqXHR) ->
        $('body').append "Successful AJAX call: #{data}"

there is something wrong with the above code,I can't compile it into js
