register_activation_hook in construct doesn't work

Question

I have an question about register_activation_hook in construct.

I have read, that this should be possible, but I don't know, currently nothing will be written to the error_log (for debugging).

Look here, the author say it should work http://www.plulz.com/how-to-create-a-plugin-for-wordpress

Here's my code

<?php
abstract class LW_Capability{
    const NAME = 'Capability';

    public function __construct(){
        register_activation_hook(
            __FILE__,
            array(
                $this,
                'activate'
            )
        );

        register_deactivation_hook(
            __FILE__,
            array(
                $this,
                'deactivate'
            )
        );
    }

    public function activate(){
        error_log('LW_Capability->activate');
    }

    public function deactivate(){
        error_log('LW_Capability->deactivate');
    }


}

class CapabilityEditRessource extends LW_Capability{
    const NAME = 'EditRessource';
}
?>

What do I do wrong? If I add an "die('parent')" to the LW_Capability, it will die. The Plugin can't be activated then (WP Blocks because of output).

Anyone here who does somthing similar?

Would be happy to hear from you.

register_activation_hook(
        __FILE__,
        array(
            $this,
            'activate'
        )
    );

    register_deactivation_hook(
        __FILE__,
        array(
            $this,
            'deactivate'
        )
    );

could just be used in the main-file of the plugin ^^

I modifyed it to

register_activation_hook(
    __FILE__,
    array(
        $MyPluginInstance,
        'activate'
    )
);

register_deactivation_hook(
    __FILE__,
    array(
        $MyPluginInstance,
        'deactivate'
    )
);

And this functions calls manually the register / unregister-functions of the capability-class
