Usage with NativeScript-Vue

I'm new to NativeScript and I'm starting with Vue, how do I use it with NativeScript-Vue?

I tested like this, but got no result
```
<template>
  <Page 
    xmlns="http://schemas.nativescript.org/tns.xsd" 
    xmlns:mtf="nativescript-masked-text-field">
    <mtf:MaskedTextField v-model="cpf" />
  </Page>
</template>
```
