title: vee-validate not working with bootstrap-vue
body: <p>I'm trying to use vee-validate for form validation with bootstrap-vue, and cannot get anything to work. Basically, I want to do:</p>
  
  <pre><code>&lt;b-form-input v-model="emailText"
                placeholder="Enter email"
                v-validate="'required|email'"
                name="email"
                type="text"&gt;
      &lt;b-row&gt;
          &lt;span&gt;{{ errors.first('email') }}&lt;/span&gt;
      &lt;/b-row&gt;
  &lt;/b-form-input&gt;
  </code></pre>
  
  <p>But I don't see anything when I type a non-email address in the field. However, if I change:</p>
  
  <p><code>b-form-input</code> to <code>input</code></p>
  
  <p>then everything works. Is there a workaround for this behavior? Any help would be greatly appreciated.</p>
