Livewire lost data when emit event

Question

i'm having a problem when i emit event from javascript to Livewire.

In my mount function i'm storing plan public propertie, when i emit the Livewire.emit('newSubscription', setupIntent.payment_method); event from javascript to my component and i trying to get the plan propertie the value is the model but with empty properties.

Pay.php

class Pay extends Component
{
public $paymentMethod;
public $slug;
public $publicKey;
public $interval;
public $plan;
private $p;
public $payWithNewCard = false;

protected $listeners = ['newSubscription'];

public function mount($slug, $interval)
{
    $this->publicKey = config('cashier.key');
    $this->slug = $slug;
    $this->interval = $interval;

    $user = auth()->user();

    //Check if the user has a subscription
    if ( auth()->user()->subscribed('default') ) {
        return redirect()->route('billing.subscription');
    }

    if ( $interval != 'month' && $interval != 'year' ) {
        return redirect()->route('billing.premium');
    }

    //Get plan
    $this->plan = Product::select('products.slug', 
    'products.trial_period_days', 'prices.currency', 'prices.interval', 
    'products.stripe_product_id as product', 
    'products.name', 'prices.amount', 'products.trial_period_days', 
    'prices.stripe_price_id', 'prices.id as price_id')
    ->where('products.active', '=', '1')
    ->where('prices.active', '=', '1')
    ->where('products.slug', '=', $this->slug)
    ->where('prices.interval', '=', $this->interval)
    ->join('prices', 'products.id', '=', 'prices.product_id')->first();

    dump($this->plan);
    //If plan doesn't exists, redirect to premium
    if ( !$this->plan ) {
        return redirect()->route('billing.premium');
    }
}

public function render()
{
    return view('livewire.billing.pay', [
        'intent' => auth()->user()->createSetupIntent()
    ]);
}

public function newSubscription($paymentMethod)
{
    try {
        //TODO: Validate only trial in first time
        $user = auth()->user();

            //If user has payment method
        if ( $user->hasPaymentMethod() ) {
            $user->addPaymentMethod($paymentMethod);
        } else {
            $user->updateDefaultPaymentMethod($paymentMethod);
        }
        dd($this->plan);
        if ( $this->plan->trial_period_days ) {
            $result = $user
            ->newSubscription('default', $this->plan->price_id)
            ->trialDays($this->plan->trial_period_days)
            ->create(($paymentMethod) ? $paymentMethod : '');
        } else {
            $result = $user
            ->newSubscription('default', $this->plan->price_id)
            ->create(($paymentMethod) ? $paymentMethod : '');
        }
            
            return redirect()->route('billing.success');
        
    } catch ( IncompletePayment $exception ) {
        return redirect()->route(
            'cashier.payment',
            [$exception->payment->id, 'redirect' => route('billing.index')]
        );
    }
