A stored procedure is returning 2 output parameter. I tried to catch them in DAL using DAAB but couldn't succeed. Actually control did not returned on next lines. Please guide me.

using (DbCommand dbCommand = db.GetSqlStringCommand("p_AddLeaveApplication"))
            {
                dbCommand.CommandType = CommandType.StoredProcedure;
                db.AddInParameter(dbCommand, "@EmployeeId", DbType.Int16, leave.EmployeeId);
                db.AddInParameter(dbCommand, "@DateTo", DbType.Date,string.Format("'{0:yyyy-MM-dd HH:mm:ss}'",  leave.DateTo));
                db.AddInParameter(dbCommand, "@DateFrom", DbType.Date, string.Format("'{0:yyyy-MM-dd HH:mm:ss}'", leave.DateFrom));
                db.AddInParameter(dbCommand, "@LeaveType", DbType.String, leave.LeaveType);
                db.AddOutParameter(dbCommand, "@Result", DbType.Int16, 1);
                db.AddOutParameter(dbCommand, "@LeaveId", DbType.Int16, 1);
                db.ExecuteNonQuery(dbCommand);
                LeaveId = Convert.ToInt16(db.GetParameterValue(dbCommand, "@LeaveId"));
                return result = Convert.ToInt16(db.GetParameterValue(dbCommand, "@Result"));
            }
