Facebook SDK: FB.Feed not posting

Hi! I finished my game. Now I want to make it social. Posting to twitter is easy, but I have problem with facebook.

I created an app on facebook dev, I have key-hash, key-store, I don't have any errors in console. I made enviroment variables with paths to JDK and OpenSSL.

I think that there's something wrong with my code (it's from SDK example) but I don't know what.

 using UnityEngine;
 using System;
 using System.Collections;
 using System.Collections.Generic;
 using System.Linq;
 
 public sealed class FacebookShare : MonoBehaviour {
     #region FB.Init() example
     
     private bool isInit = false;
     
     void Awake ()
     {
         CallFBInit();
     }
 
     private void CallFBInit()
     {
         FB.Init(OnInitComplete, OnHideUnity);
     }
     
     private void OnInitComplete()
     {
         Debug.Log("FB.Init completed: Is user logged in? " + FB.IsLoggedIn);
         isInit = true;
     }
     
     private void OnHideUnity(bool isGameShown)
     {
         Debug.Log("Is game showing? " + isGameShown);
     }
     
     #endregion
     
     #region FB.Login() example
     
     private void CallFBLogin()
     {
         FB.Login("email,publish_actions", LoginCallback);
     }
     
     void LoginCallback(FBResult result)
     {
         if (result.Error != null)
             lastResponse = "Error Response:\n" + result.Error;
         else if (!FB.IsLoggedIn)
         {
             lastResponse = "Login cancelled by Player";
         }
         else
         {
             lastResponse = "Login was successful!";
         }
     }
     
     private void CallFBLogout()
     {
         FB.Logout();
     }

This script is attached to NGUI button. In editor it works but on device it only asks to login and permision. Then nothing happens.
