How to Combine Input of Number and Password in Ionic (Cordova-based)

Based on this docs :

http://ionicframework.com/html5-input-types/

There are many types of HTML5 input. The 2 of them are Number and Password. How to combine them?

I am not sure whether the tag-attribute value is similar with Cordova or not, because Ionic Framework is based on Cordova.

Use AngularJS ng-pattern directive. 

Use following code pen:

Seems like this question is answered before: in another post

I do not know however if this works correctly with ionic, but I wouldn't know why it shouldn't :)

JS can handle number on the fly

<input type="password" name="password" onkeyup="if (/\D/g.test(this.value)) this.value = this.value.replace(/\D/g,''),alert('only numbers')" id="password" value="" placeholder="Enter your numeric password">
