Using Query Scope to filter results within Laravel Blade template

I'm using query scope within my controllers in some places but now i'm trying to filter down some results within my blade template. My model has a location which has orders. I pass the location to the blade template and then use the following:

@foreach( $location->orders->datesearch('delivered_at','2015-10-01','2015-10-15') as $order )
    {{ $order->order_number }}<br />
@endforeach

And here's an excerpt from my Order Model

class Order extends Model {

    public function location()
    {
        return $this->belongsTo('App\Location', 'location_id');
    }

   public function scopeDatesearch($query,$datesearch,$search_date_start,$search_date_end)
       {
           return $query->whereBetween($datesearch, [$search_date_start, $search_date_end])->get();
       }
}

Location hasMany Orders as well.

The error I'm getting is:

FatalErrorException in 56b3a0ff15f6ddc28458248fd0728a27 line 5:
Call to undefined method Illuminate\Database\Eloquent\Collection::datesearch()

I did find this similar posting which seems to indicate what I'm doing should work.
