Numeric Keyboard does not show up in Android

[junerockwell]

Below is the code for the input[type=text]. The keyboard works as expected on iOS, but it does not show up on Android. Therefore, I can type any character from the keyboard (non-numericals and decimal point).

<input
      type="text"
      pattern="[0-9]*"
      decimal="true"
      [attr.placeholder]="field.placeholder"
      [formControlName]="field.name" />

See Screenshot:

Android Device: Samsung Galaxy S6
Android version: 7.0
Cordova: v6.5.0
AngularJS: v5 with Ionic 3.x
Cordova-Android: v6.1.2
Cordova-iOS: v4.3.1

Please make an Android compatible one. This repo seems to only have one for iOS but there is nothing for Android. The community would appreciate it, thanks!
