What is a good cross platform development framework and stack that works well on Flame, Android, and iOS?

Does this list work ok?

- PhoneGap/Cordova for native access - jQuery Mobile for UI widget - Bootstrap3 for responsive layout - jQuery for DOM access - Knockout for dynamic update - Toastr for non-blocking alerts - Amplify for data/storage/messaging - Underscore for general

Is html template system needed? Given that jQuery Mobile widgets are already used to build the UI.
