Posting to Facebook wall using HttpMethod.POST unity3D

well I am using unity and trying to post on my wall... I imported the Facebook sdk and i used the code in their docs which is

int score = 10000;

var scoreData = new Dictionary () {{"score", score.ToString()}};

FB.API ("/me/scores", HttpMethod.POST, LogCallback, scoreData); and i have allowed the publish settings (when i logged in ) still nothing happens .. so here is my code exactly

     void Awake(){
     FB.Init (SetInit, OnHideUnity);
 
 
 
 }
 
 private void SetInit(){
     Debug.Log("IN");
 
 
 
 }
 
 private void OnHideUnity(bool isGameShown){
 
     if (!isGameShown) {
         Time.timeScale=0;
 
     }
 
 
     else {
 
         Time.timeScale = 1;
     }
 
 }
     void FBlogin()
 {if (!FB.IsLoggedIn) {
 
                     FB.Login ("email,publish_actions", AuthCallback);
             }
     else {  if (FB.IsLoggedIn) {
             //  Screen.orientation = ScreenOrientation.LandscapeRight;
 
 
             Dictionary<string,string> score1=new Dictionary<string, string>();
             score1.Add("Score","100");
 
 
 
             FB.API ("/me/scores",Facebook.HttpMethod.POST, AuthCallback, score1);
             Debug.Log("Okay");
 
 
 
 
         } 
 
 
             }
 }
 
 
 void AuthCallback(FBResult result){
     if (FB.IsLoggedIn) {
     //  Screen.orientation = ScreenOrientation.LandscapeRight;
 
         int score = 10000;
 
         Dictionary<string,string> scoreData = 
         new Dictionary<string, string>() {{"score", score.ToString()}};
 
         FB.API ("me/scores", HttpMethod.POST, LogCallback, scoreData);
 
 
         Dictionary<string,string> scoreData1 = 
         new Dictionary<string, string>() {{"score", "0"}};
 
 
 
 
 
     } 
 
 
     else {
         Debug.Log("FB LOGIN ERROR");        
 
 
     }
 
 }
