Volley JsonObjectRequest Post request not working

I am using android Volley for making a request. So I use this code. I don't understand one thing. I check in my server that params is always null. I consider that getParams() not working. What should I do to solve this issue.

 RequestQueue queue = MyVolley.getRequestQueue();
        JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST,SPHERE_URL,null,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        System.out.println(response);
                        hideProgressDialog();
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                      hideProgressDialog();
                    }
                }) {
            protected Map<String, String> getParams() throws AuthFailureError {
                Map<String, String> params = new HashMap<String, String>();
                params.put("id","1");
                params.put("name", "myname");
                return params;
            };
        };
        queue.add(jsObjRequest);

try to use this helper class

import java.io.UnsupportedEncodingException;
import java.util.Map;    
import org.json.JSONException;
import org.json.JSONObject;    
import com.android.volley.NetworkResponse;
import com.android.volley.ParseError;
import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.Response.ErrorListener;
import com.android.volley.Response.Listener;
import com.android.volley.toolbox.HttpHeaderParser;

public class CustomRequest extends Request<JSONObject> {

    private Listener<JSONObject> listener;
    private Map<String, String> params;

    public CustomRequest(String url, Map<String, String> params,
            Listener<JSONObject> reponseListener, ErrorListener errorListener) {
        super(Method.GET, url, errorListener);
        this.listener = reponseListener;
        this.params = params;
    }

    public CustomRequest(int method, String url, Map<String, String> params,
            Listener<JSONObject> reponseListener, ErrorListener errorListener) {
        super(method, url, errorListener);
        this.listener = reponseListener;
        this.params = params;
    }

    protected Map<String, String> getParams()
            throws com.android.volley.AuthFailureError {
        return params;
    };

    @Override
    protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
        try {
            String jsonString = new String(response.data,
                    HttpHeaderParser.parseCharset(response.headers));
            return Response.success(new JSONObject(jsonString),
                    HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException e) {
            return Response.error(new ParseError(e));
        } catch (JSONException je) {
            return Response.error(new ParseError(je));
        }
    }

    @Override
    protected void deliverResponse(JSONObject response) {
        // TODO Auto-generated method stub
        listener.onResponse(response);
    }
}

In activity/fragment do use this

RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
CustomRequest jsObjRequest = new CustomRequest(Method.POST, url, params, this.createRequestSuccessListener(), this.createRequestErrorListener());

requestQueue.add(jsObjRequest);
