Setting keyboard types

[solcacorona]

Regards,

I am creating a newTextField field for the user to enter a phone number, and I would like to display the numerical virtual keyboard to the user.

In CoronaSDK I can use:

local myPhone = native.newTextField (50, 150, 220, 36)
myPhone.inputType = "phone"

How can I display the keyboard using MUI?

I have used the option:

inputType = "phone"

but it does not work.

Thanks in advance for the answer, and again this is a BIG WORK!!
