Use ionic keyboard on INAPPBROWSER's blank window (iOS version)

Hi! I 'm designing a web into a php framework and if i open it with the plugin inappbrowser (into a blank page to inject javascript code) when i pick up in a select field and the keyboard displays (if i’ve a modal selected) this is ruining all the view…

The modal lost the focusses and all the page is ruined in general… How can i change this?

Thanks
