Tool tip not hiding in IOS brower but working in firefox,chrome ,IE and safari

Tool tip not hiding in IOS brower but working in firefox,chrome ,IE and safari

hi..

      I used jquery tooltip plugin to show tooltip in my application, on mouseover that tooltip will visibles, on mouseout that tooltip hides.This is working fine in   firefox,chrome ,IE and safari browsers.
But in IOS browser that tooltip opening properly but not closing on mouseout.
    But in IOS browser     Tapping/Onmouseover on the one text causes a tool tip to appear, which does not close on tapping elsewhere. The tool tip does not close even after tapping on somewhere which causes another popup to appear. It stays even when the user navigates to a different page. The tool tip closes only when the user taps on the tool tip itself.

regards,
Jebin
