Angular and Coffee(my first time using coffee)

  $scope.addUser = (userId,chatroomId)->
    data = {user_id: userId, chatroom_id: chatroomId}
    $http.post(chatroomId + "/memberships", data).then (response) ->
      userData = response.data.user
      console.log userData
      $('#' + userData.id + '-add-member').parent().remove()
