Cannot JOG Plus/Minus move in TeleOp mode

I'm trying to configure an existing LinuxCNC machine (simple XYZ) in manual mode using physical mechanical switches for axis selection and Jog Plus/Jog Minus.
It works in joint mode.
But it doesn't seem to work in TeleOp mode. 

I operated same things from using HAL Pin manually without wireing configuration, but I got the same result.

What I did using HAL Pin (in TeleOp mode)  was..
1) confirm manual mode in LCNC. (all axis homed )
2) Turn on/off some pins in Show Hal configuration (N=axis char)

halui.axis.jog-speed ( set to 500 )
halui.axis.N.selected
halui.axis.N.is-selected
halui.axis.N.plus/minus

I tried another method using halui.axis.selected.plus/minus, but same.

Should I use another pins?
What am I missing ?
Which pin should I check ?
Could you guys help me solve this problem, please ?
 

Thanks !

I was using LinuxCNC Ver 2.4.5 at that time.
But Today, after I just upgraded to Ver 2.4.8, everything works well.
