I have the following code for my `Sessions` model:

```
module.exports = {

  attributes: {

  },
  afterCreate: function(value,next) {
    next();
  }

};

```

And the following `Sessions` Controller:

```
module.exports = {

  saveSession: function(res,req) {
    console.log('in save');
  }
};

```

I want to save a value to a user's session `afterCreate`

How can I call the `saveSession` function from my model? I tried `Sessions.saveSession()` but it doesn't work.
