[ndnSIM] ndnSIM: hijacker doesn't work and empty PIT

I'm working on a simple tree topology. I want that one specific node
(a router) works like an hijacker, so I tried to set this node to
Hijacker but this node works like a normal node and forward everything
to the correct destination.

Furthermore I can't fill the PITs of every node of the topology, if I
try to simulate the application, every PIT is empty, but with the
visualizer I can see that every packet pass toward every node.

This is my code:

// Install CCNx stack on all nodes
    ndn::StackHelper ccnxHelper;
    ccnxHelper.SetForwardingStrategy ("ns3::ndn::fw::BestRoute");
    ccnxHelper.SetPit ("ns3::ndn::pit::SerializedSize", "MaxSize", "100");
    ccnxHelper.SetContentStore ("ns3::ndn::cs::Lru", "MaxSize", "1");
 // Content Store OFF
    ccnxHelper.InstallAll ();

    // Installing global routing interface on all nodes
    ndn::GlobalRoutingHelper ccnxGlobalRoutingHelper;
    ccnxGlobalRoutingHelper.InstallAll ();

    // Getting containers for the consumer/producer
    Ptr<Node> consumer1 = Names::Find<Node> ("leaf-1");
    Ptr<Node> consumer2 = Names::Find<Node> ("leaf-2");
    Ptr<Node> consumer4 = Names::Find<Node> ("leaf-4");
    Ptr<Node> producer = Names::Find<Node> ("leaf-3");
    Ptr<Node> router3 = Names::Find<Node> ("rtr-3");
    Ptr<Node> router2 = Names::Find<Node> ("rtr-2");
    Ptr<Node> router1 = Names::Find<Node> ("rtr-1");

    ndn::AppHelper consumerHelper ("ns3::ndn::ConsumerWindow");
    consumerHelper.SetAttribute ("Window", UintegerValue (100));
    consumerHelper.SetAttribute ("Size", StringValue("0.1"));
    consumerHelper.SetPrefix ("/rtr-3/leaf-3");
    consumerHelper.Install (consumer1);
    consumerHelper.SetPrefix ("/rtr-3/leaf-3");
    consumerHelper.Install (consumer2);

   //hijaker router1
   ndn::AppHelper hijackerHelper ("Hijacker");
   hijackerHelper.Install (router1);

   //attacker consumercbr
   ndn::AppHelper consumerHelper_attack ("ns3::ndn::ConsumerCbr");
   consumerHelper_attack.SetAttribute ("Frequency", StringValue ("1"));
   consumerHelper_attack.SetPrefix ("/rtr-3/leaf-3");
   consumerHelper_attack.Install (consumer4);

   //producer leaf-3
   ndn::AppHelper producerHelper ("ns3::ndn::Producer");
   producerHelper.SetAttribute ("PayloadSize", StringValue("1024"));

   ccnxGlobalRoutingHelper.AddOrigins ("/rtr-3", producer);
   producerHelper.SetPrefix ("/rtr-3");
   producerHelper.Install (producer);

   // Calculate and install FIBs
   ccnxGlobalRoutingHelper.CalculateRoutes ();

   Simulator::Schedule (Seconds (1.0), printPitStats, router1);
//print statistics about PIT
   Simulator::Stop (Seconds (5.0));
   Simulator::Run ();
   Simulator::Destroy ();

Where am I wrong?
