Button under the current page getting clicked/tapped

I'm using sencha touch 2.3.1

I have a button on a page and clicking it will open a new page (above the current page).

But when I click/tap on the new page in the region where the button is ( in the original page ) , the button is still getting clicked.

And a new view of the same page is being opened.

I'm facing this problem only in windows phone, it works fine in android, IOS and all browsers (including IE) through IIS.

Please help me resolve this.

Thank you.
