Keyboard and regx for TextInput

I want to let the user enter text but only open the number keyboard
And to pass the regx for TextInput (only number without other chars like -?...)

I thought TextInput has a {inputType:"number"} parameter? Have you tried it?

I just tested this and doesn't bring up number only keyboard.

yes but you can type -? and more chars from the number keyboard

EDIT

So after more testing the created input doesn't seem to be a problem. Need to look into further.

for my code i cheange the regx and its ok
but i think all ZIM creators need that.

Sorry - what does the regx have to do with anything? What are we talking about?
