text input field update based on another text input

I can't seem to get this working. I want to have one TextInput that's updated when another one is changed by the user. .

 TextInput::make('payment_before_discount')
                ->prefix('$')
                ->live(true)
                ->reactive()
                ->default($this->paymentData['total_before_discounts']),
           
            TextInput::make('payment_amount')
                ->label('Net Payment Amount')
                ->disabled()
                ->prefix('$')
                ->live()
                ->reactive()

 TextInput::make('payment_before_discount')
                ->prefix('$')
                ->live(true)
                ->reactive()
                ->default($this->paymentData['total_before_discounts']),
           
            TextInput::make('payment_amount')
                ->label('Net Payment Amount')
                ->disabled()
                ->prefix('$')
                ->live()
                ->reactive()

When a user changes the payment_before_discount input, I want the value of the payment_amount input to update as well. I've tried using afterStateUpdated and also the default method, but can't seem to get it working.

something like this?

->afterStateUpdated( fn(Set $set, $state) => $set('payment_amount', $state))

->afterStateUpdated( fn(Set $set, $state) => $set('payment_amount', $state))

live() is the same as reactive(), but newer and more aligned with Livewire
