When bootstrap popup is clicked, it open and closed in series on webview of Android 4.2

We used bootstrap css in our web project. Our android app runs our web project in webview . Everything is ok under android 4.2.x .However on android 4.2(Samsung s4 , google tablet) popup open and closed in series when popup is clicked. i found two links about subject. However these do not solve our problem. I think that this problem is created by android 4.2 bug.
