morphMany Issue (Now I receive a JSON output with the filtered object, when I call: $model->metas->meta_key)

Meta.php

<?php

class Meta extends Eloquent {
	public function newCollection(array $models = array())
	{
		return new MetaCollection($models);
	}
}

MetaCollection.php

<?php
use Illuminate\Database\Eloquent\Collection;

class MetaCollection extends Collection {

    public function __get($name)
    {
    	$this->temp = $name;

        return $this->filter(function (Meta $item) {
        	return $item->key == $this->temp;
        });
    }
}

Resort.php

<?php

class Resort extends  Eloquent {
    public function metas()
	{
		return $this->morphMany('Meta', 'metable');
	}
}
