customerRepositoryInterface->save does not save attribute “is_active”

[jens_sch]

I'm trying to update "is_active" attribute but nothing happens in the database. I don't get an error message either. What am I doing wrong?

public function changeStatus($statusData)
{    
    $customer= $this->customerRepositoryInterface->getById($statusData['id']);    
    $customer->setData('is_active', 0);
    }
    try{        $this->customerRepositoryInterface->save($customer);
    } catch (\Exception $e ){
        throw new \Exception($e->getMessage());  
    }
}
