reset height

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I have two buttons, one use this code: $('.scroll').iScroll({height:200});

The other button use this one: $('.scroll').iScroll({height:200});
2. When I press the first button the scroll appears, great.
3. But when I press the second button nothing happens, I wish the height is 
adjusted to the new data 

What is the expected output? What do you see instead?
I expect to see the scroll div with the original height. No react.

What version of the product are you using? On what operating system?
ver.01 rev.016. Windows XP
