wire.loading.remove on Button::macro()

[andersoncstd]

Sorry if I'm being dumb , but I try to follow the docs, but it is not working. The HTML render the attibutes, the event got dispatched, but the button are not removed on loading.

use PowerComponents\LivewirePowerGrid\Button;
Button::macro('loadingRemove', function () {
    $this->attributes([
        "wire:loading.remove"=>"",
        "wire:target" => "mostrar-criar-contrato-toggle",
    ]);
    return $this;
});

And then:

public function header(): array
    {
        return [
            Button::add('novo-contrato')
                ->slot('Adicionar contrato')
                ->icon('default-plus-square', ['id' => 'my-custom-icon-id', 'class' => 'w-4 font-bold mr-2'])
                ->class('bg-green-600 hover:bg-green-700 font-semibold text-white p-2 mx-2 rounded-md flex items-center justify-center space-x-2 disabled:opacity-50')
                ->dispatch('mostrar-criar-contrato-toggle',[])
                ->loadingRemove(),
        ];
    }

If a just change the macro to wire:loading, the button gets removed but it don't appear again.
The spinnig whell it's not showed as well.

Any help is apprecieted!
