Hello. Using JQM 1.2.0. Side JS libraries are not used at the page.
Some code opens popup (data-role="popup") on tap at list item of data-role="listview" element. The problem is that popup is automatically closed right after it opens.

Default JQM functionality wraps markup into radiobutton widget - ok, then a click on some unchecked radio turns it to checked state - ok, but then i can't uncheck it by click on it again. There's no additional code used to manipulate the markup above.
