Quill with Vue v-model without npm

Question

I'm using vuejs with quill.

I'm not using npm or any other build tools, only linking vuejs and quill.min.js in the header of my html.

If quill works, v-model doesn't and vice versa.

    <div id="editor">
       <input class="textarea" v-model="email_content">
    </div>

and

  <input id="editor" class="textarea" v-model="email_content">

or

<div id="editor">
    <textarea class="textarea" v-model="email_content"></textarea>
</div>

doesn't do the job. Console doesn't show any error.
