entering data in web api

I have a SPA application and it consumes a REST API done in ASP.NET WebAPI.

When trying to perform an insert in the API, the following error is returned:

  

Response for preflight has invalid HTTP status code 405

In web.config of WebAPI I configured like this:

<customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, OPTIONS" />
</customHeaders>

I do not know why this happens.

Non-angled:

 $scope.inserirCarro = function () {
    var carro = {
        CarroNome: $scope.nome,
        MinCod: $scope.selectMin
    };

    var carroData = crudService.IncluirCarro(carro);
    carroData.then(function (data) {
        getCarros();

        if (data.status == 200) {
            toastr["success"]("Registro cadastrado com sucesso!", "Sistema");
        }

    }, function () {
        toastr["error"]("Erro ao incluir!", "Sistema");
    });
}

Non-angular service:

 this.IncluirCarro = function (carro) {
    var response = $http({
        method: "post",
        url: urlAPI + "/api/v1/carros/postcarro",
        data: JSON.stringify(carro),
        dataType: "json"
    });
    return response;
}
