Accessing event arguments in notification funciton like bind and unbind

```
'created' : {
    "draft" : function(){
return this.drafted;
}, 
    "publish" : function (projectid) {
      return this.published;
    }
  },
```

If I want to access `projectid` in bind, how can I do that? Or is there any way that I can pass data to the bind() function?
I need this for a couple of use cases. For instance, I want to log every transition along with the specific data.
