I had tried above handling event like this also but then also result is same

  if( event & TEMPERATURE_SENSING_EVENT)
  {
    pData = "@TEM####" ;
    zb_SendDataRequest( 0xFFFE, SENSOR_REPORT_CMD_ID, 8, pData, 0, AF_ACK_REQUEST, 0 );    
    event &= ~TEMPERATURE_SENSING_EVENT;	//resetting temperature sensing event
  }
