The scrolling on the actual device is controlled by touch events. Browsers use mouse events. You may need to use something like fastclick.js to emulate those touch events.
Using chrome you emulate touch events. Use the information from the following links to emulate those touch events.
If it still doesn't work then let me know.
Where scrolling is not working? Screen with large item list? A large text? A form with controls that exceeds screen size?
I have several apps using bootstrap and scroll is working. If you tell me more I may give you a mockup of a simple app.
