How to create button with timer multi-function

You can refer my answer in http://e2e.ti.com/support/wireless_connectivity/f/158/p/381943/1346479.aspx#1346479

I want to execute 'reset' after press and hold button for 5 sec. I still cannot get it to work. This is my code:

#define KEYHOLD_EVT  0x0100    //define event for key hold

int KeyPressCnt=0; //declare global variable for joystick hold checking.

uint16 zclSampleLight_event_loop( uint8 task_id, uint16 events )
{

	.....

	if ( events & KEYHOLD_EVT )
	{
		if ( HAL_PUSH_BUTTON2()) //=== HAL_KEY_SW_2
		{
			KeyPressCnt++;
			if (KeyPressCnt>=5)
				{
				//Key hold for 5 second
				zclSampleLight_BasicResetCB();
				}
			else
				osal_start_timerEx( zclSampleLight_TaskID, KEYHOLD_EVT, 100);	
		}
		return ( events ^ KEYHOLD_EVT );
	}

	// Discard unknown events
	return 0;
}

osal_start_timerEx uses milli-seconds so you should change osal_start_timerEx( zclSampleLight_TaskID, KEYHOLD_EVT, 100) osal_start_timerEx( zclSampleLight_TaskID, KEYHOLD_EVT, 1000.)

I did that. It still did not work. Is there a sample code to implement hold button anywhere?
