Show password in input

Hello,

I have a problem with the following code. When compiling in Preview is working, but when compiling for Android is not working.
Clicking on the button should show the password that is in the input.

Code:

  <JavaScript>
    var Observable = require('FuseJS/Observable');
    var IsPassword = Observable(true);

    function showPass(){
      IsPassword.value = !IsPassword.value;
    }

    module.exports = {
      IsPassword:IsPassword,
      showPass:showPass
    }
  </JavaScript>

  <Button Text="Show" Alignment="Right" Clicked="{showPass}"/>
  <TextInput PlaceholderText="Password" IsPassword="{IsPassword}" />

I need some help getting it resolved as soon as possible.
