With query Issue in Eloquent

I have following query which works fine and gives result for StatusType

AddOnModel::with('StatusType')->get();

But when I write below, it does not bind StatusType Records

AddOnModel
::select(\DB::Raw('A.AddOnID, A.AddOn, Count(R.AddOnID) as Total'))
->from( 'tblAddOn as A' )
->with('StatusType')
->leftjoin( 'tblrevenue as R', \DB::raw( 'R.AddOnID' ), '=', \DB::raw( 'A.AddOnID' ) )
->groupBy("A.AddOnID", "A.AddOn")->get();

The part which does not work is this one: ->with('StatusType')

Am I doing something incorrectly?

Here is the Model

class AddOnModel extends Model {

    public $table = 'tbladdon';
    public $primaryKey = 'AddOnID';
    public $timestamps = true;

    public function StatusType() {
        return $this->hasOne('\StatusTypeModel', 'StatusTypeID', 'StatusTypeID');
    }
}
