Title: Add a callback in a model for when a row is created / deleted / updated 

The way I'd see it, is something like this.

```php
on('create', function() {
// ...
});

$this->on('delete', function() {
// ...
});

$this->on('update', function() {
// ...
});
}
}
```

The `on` method should be protected.

There will also be a `trigger` method to trigger an event.
