Support for numeric keyboard via input[type=number]?

Hi!

Thanks for the great component, it worked right out of the box!
One question:
The HTML `<input type=number>` will make for example Android browsers open a keyboard with only numbers as available input. No other characters. This is a great thing for the end user.

Is there any way to achieve this via your component? I tried adding type=number but that didn't work. 

Thanks again!
