插入后没有回调

Question

我不确定为什么我在Collection.insert之后没有收到来自服务器的回调。我一直指的是this stack，但我似乎无法弄清楚如何获得成功或错误插入的回调。

Server.js

Meteor.startup(function () {

  // Using matb33:collection-hooks, this will record a timestamp before
  // each resonance is created     
  Resonance.before.insert(function(userId, doc){
      doc.createdAt = new Date();
  })

  if (Resonance.find().count() === 0) {
    for (var i = 0; i < resonance.length; i++)
      Resonance.insert({ email: resonance[i].email }, function(error, result) {
        if (error) console.log ('there was an error!');
        if (result) console.log ('Success!!!');
      });
  }
});
