JS API integration with Sencha Touch

I'm using Sencha Touch to build mobile app. And my requirement is using LinkedIn JS Api to validate the user and do operations according to the user. I'm having no problem in using the API in browser. But I have a problem when 'Sign In' button clicked, the popup window for authentication is not appeared because of Sencha Touch component didn't recognize the event or vice versa.

I have attached the screenshot.

LinkedIn.jpgThe window that's asking for linked in credentials is opened in a new window of the browser and not inside the emulator which is behind the window. And i want to open the window inside the emulator not on the browser.

Is it possible to do LinkedIn oauth in sencha?
