How to make a Shell Script create a copy and terminate itself?

Question

So far I used

trap " call function" 2 

fucntion
{
./test.sh
exit
}

but it never reaches the exit line and a whole bunch of process piles up any one got any idea?

I tried & (bg) but i need to be able to keep doing it , the bg only allows me to do it once The point of it is when i type ctrl C it should terminate the original test.sh but it should also call itself before terminating hence create a new process.

This is what i have so far

while [ 1 ]
do

count=0;
echo $count
count=`expr $count + 1`

done

trap "restart" 2 ( for the ctrl c)

restart()
{

 ./callitself.sh
 exit ( it never reaches here therefore it doesnt kill the original process which is what i need otherwise it works fine)

}
