Updating icons on the taskbar

I hope this is the correct category for my problem. If not, please send me in the right direction.

I have a small application that I would like to have reflect a status through the icon it displays. I can make this work just fine as long as the icon is placed on the desktop, but id I place it on the taskbar it stops updating.

Here is a short script that I (I hope) explains what I mean. If you place this script in your crontab to be run every minute, then the icon on the desktop updates, but the icon on the taskbar does not:
#!/bin/sh -x
## Test on how to switch icons on condition

ICONFILE=$HOME/Desktop/DATA_STATUS.desktop
KICKERFILE=$HOME/.kde/share/apps/kicker/DATA_STATUS-2.desktop
minute=`date +%M`
remainder=`expr $minute % 2`

if [ $remainder == 1 ]; then
# echo "$minute is an odd number"
sed s/Icon=error/Icon=gnome-favorites/g $ICONFILE > /tmp/qwe.$$
else
# echo "$minute is an even number"
sed s/Icon=gnome-favorites/Icon=error/g $ICONFILE > /tmp/qwe.$$
fi
mv /tmp/qwe.$$ $ICONFILE
cp $ICONFILE $KICKERFILE

##### End script

I think the problem may be that I don't know how to refreash the taskbar.
Any help would be much appreciated!
