Button Direction changing

Hie,
I just downloaded your plugin, everything is working fine the only problem i am facing is when i click on the button to paginate that button comes on 1st place.

For eg: 1 2 3 4 5 6 7
if i click on 5, then automatically it becomes
5 1 2 3 4 6 7.
That 5 comes on the 1st position.
Hope for your reply soon.
Thanks in advance.
