Problem with dispatch on parent component

Hi,

I've a component (lead-not-assigned.blade.php)

 <?php

use App\Enums\DossierCaseEnum;
use App\Models\DossierModel;
use Livewire\Attributes\Computed;
use Livewire\Attributes\Layout;
use Livewire\Attributes\On;
use Livewire\Attributes\Title;
use Livewire\Component;

new
#[Layout('layouts::admin.app'), Title('Lead not assigned')]
class extends Component {

    use \Livewire\WithPagination;

    #[Computed]
    #[On('lead-assigned')]
    public function dossiers()
    {
        return DossierModel::query()
            ->where('case', DossierCaseEnum::NOT_ASSIGNED_LEAD)
            ->orderBy('created_at', 'ASC')
            ->paginate(15);
    }
};
?>

<div class="max-w-7xl h-full">
    <div class="flex items-center justify-between">
        <div>
            <flux:heading size="xl">Leads not assigned</flux:heading>
            <flux:text class="mt-2">Manage your not assigned leads</flux:text>
        </div>
    </div>

    <div class="grid grid-cols-2 gap-6 mt-8">
        @foreach($this->dossiers as $dossier)
            <livewire:pages::admin.leads.lead-not-assigned-card :$dossier
                                                                :wire:key="$dossier->id"
                                                                :lazy.bundle="$dossier->iteration > 9"
            />
        @endforeach
    </div>

</div>

And his child component (lead-not-assigned-card.blade.php) :

<?php

use App\Actions\Dossier\AttachInitialStatusAction;
use App\Enums\DossierCaseEnum;
use App\Models\AgencyModel;
use App\Models\DossierModel;
use App\Models\User;
use Livewire\Attributes\Computed;
use Livewire\Attributes\Lazy;
use Livewire\Component;

new
#[Lazy]
class extends Component {

    public DossierModel $dossier;
    public ?string $analyst = null;

    #[Computed]
    public function financingAmount()
    {
        return $this->dossier->getTotalLoansAttribute()
            + $this->dossier->getTotalOverdraftsAttribute()
            + $this->dossier->getTotalTreasuriesAttribute()
            + $this->dossier->getTotalDebtsAttribute();
    }

    #[Computed]
    public function analysts()
    {
        $agency_id = AgencyModel::where('is_main', true)->first()?->id;
        return User::whereHas('agencies', function ($query) use ($agency_id) {
            $query
                ->whereIn('agency.id', [$agency_id]);
        })->orderBy('name', 'ASC')
            ->get();
    }

    public function transfer()
    {
        $this->validate([
            'analyst' => ['required', 'exists:users,id']
        ], [
            'analyst.required' => 'Analyst is required.',
            'analyst.exists' => 'Analyst is not valid.'
        ]);

        try {
            $user = User::find($this->analyst);

            $this->dossier->sale_agent = $user->id;
            $this->dossier->case = DossierCaseEnum::DISCOVER_DOSSIER;
            $this->dossier->save();

            $this->dossier->refresh();

            $agencies = $user->agencies();
            if (0 === $agencies->count()) {
                throw new Exception('User has no agency.', 500);
            }

            AttachInitialStatusAction::execute($this->dossier, $this->dossier->case);

            $this->dossier->agency()->associate($agencies->first());
            $this->dossier->analysts()->attach($user);

            $this->reset(['analyst']);

            $this->dispatch('lead-assigned')->to('lead-not-assigned');
        } catch (\Exception $e) {

        }
    }
};
?>

        </div>
        <flux:error name="analyst" />
    </div>
</div>

But dispatch does not work ! dossiers method in parent component always display lead whereas it's not an not assigned lead anymore. Anyone has an idea ?
