error occure when implement addColumn

`function data_paging_obat_pasien() { $get = $this->input->get(); $queryBuilder = $this->query_obat_pasien($get);

	$datatables = new DataTablesCodeIgniter3($queryBuilder);
	return $datatables
	->asObject()
	->format('harga_per_obat', function($row){
		return format_uang($row);
	})
	->format('harga_obat', function($row){
		return format_uang($row);
	})
	->addColumn('status', function($row){
		return $row->status_bayar==1?"Lunas":"Belum Lunas";
	})
	->addColumn('action',function($row){
		return '<button class="btn btn-outline btn-xs btn-info" onclick="tandaiLunas(event,'.$row->idnoresep.')">Tandai Lunas</button>';
	})
	->generate(); // done
}`

when implementing addColumn it causes an error in the search feature, because the builder tries to search for an additional column that does not exist in the database table
