Set Key-Value Data from Custom Page

Hello - I have a custom page that implements a form. The page allows users to scan barcodes. I want those scanned barcodes to appear as the values in the cards field.

return $form
            ->schema([
                TextInput::make('amount')
                    ->prefix('$')
                    ->numeric()
                    ->required()
                    ->default(10)
                    ->minValue(1)
                    ->maxValue(100),
                KeyValue::make('cards')
                    ->required()
                    ->keyLabel('Card Number')
                    ->valueLabel('Barcode')
                    ->reactive()
            ])
            ->statePath('data');

public function addCard($barcode)
    {
        $barcode = preg_replace('/[^0-9]/', '', $barcode);

        foreach ($this->data['cards'] as $card) {
            if ($card == $barcode) {
                return Notification::make()
                    ->danger()
                    ->title('Card Already Scanned')
                    ->send();
            }
        }

        $this->data['cards'][$this->cardNum] = $barcode;
        $this->cardNum++;
    }

return $form
            ->schema([
                TextInput::make('amount')
                    ->prefix('$')
                    ->numeric()
                    ->required()
                    ->default(10)
                    ->minValue(1)
                    ->maxValue(100),
                KeyValue::make('cards')
                    ->required()
                    ->keyLabel('Card Number')
                    ->valueLabel('Barcode')
                    ->reactive()
            ])
            ->statePath('data');

public function addCard($barcode)
    {
        $barcode = preg_replace('/[^0-9]/', '', $barcode);

        foreach ($this->data['cards'] as $card) {
            if ($card == $barcode) {
                return Notification::make()
                    ->danger()
                    ->title('Card Already Scanned')
                    ->send();
            }
        }

        $this->data['cards'][$this->cardNum] = $barcode;
        $this->cardNum++;
    }

My page is correctly emitting the scan event to addCard, but I can't figure out how to dynamically set the cards array and get it to update on the page.
