如何在没有页面刷新jquery的情况下刷新附加数据？

I am trying to use ++ in jquery to append data, and I face a problem, I need to refresh the value again if I click other button without refresh page, how can I do that? The var count will increase as I clicked, I want to know if I can start over this count again when I click second button.I am trying to use ++ in jquery to append data,
