How to get tx,ty,tz on double clicking the scene??

Hi,

<hotspot name="spot1" style="doorspot" width="60" height="80" tx="-22" ty="15" tz="536" />


I can able to retrive tx,ty,tz values when hotspot is created statically

but when I create hotspot dynamically using atv and ath values, I can't able to get tx,ty,tz values?

Can you guide me in this ?
