Sorting not working

[jigapate]

Hello,

For whatever reason, not sure why my table doesn't sort, for symbol, dchange or pchange,

    public function fields(): PowerGridFields
    {
        return PowerGrid::fields()
        ->add('date')
        ->add('symbol', function (EodBhavData $quote) {
            return Blade::render('pages/apps.eodbhavdata._link', compact('quote'));
            })
        ->add('dchange')
        ->add('pchange', function (EodBhavData $quote) {
            return Blade::render('pages/apps.eodbhavdata._badge_pchange', compact('quote'));
            })
        ->add('total_traded_quantity')
    }

    public function columns(): array
    {
        return [
            Column::make('Date', 'date')
                ->sortable()
                ->searchable(),
            Column::make('Symbol', 'symbol')
                ->sortable()
                ->searchable(),
            Column::make('Change', 'dchange')->sortable(),
            Column::make('% Change', 'pchange')->sortable(),
            Column::make('Total Trades Qty', 'total_traded_quantity'),
        ];
    }

As per documentation, I have provided same fields for as database, but its not working,
am I missing something?

It is resolved by removing sorting query in datasourse,
