title: How to get value of vuetify number type v-text-field in template
body: <p>I am trying to pass value of v-text-field in function so I can update database but I don't know how because I am using v-for.</p>
  
  <p>Didn't know what to try.
  I can't use v-model because it will change on all items in tracker array that I am looping through.</p>
  
  <pre><code>&lt;v-card v-for="track in tracker" :key="track.title" min-width="600" tile class="pa-3 mb-2" dark&gt;
            &lt;v-card-title style="background-color: #2f2f2f"&gt;
              &lt;h3 class="white--text headline"&gt;{{ track.title }}&lt;/h3&gt;
            &lt;/v-card-title&gt;
            &lt;v-card-actions&gt;
              &lt;v-layout row wrap&gt;
                &lt;v-flex xs5&gt;
                  &lt;v-text-field min="0" step="1" type="number" label="Season" :value="track.season"&gt;&lt;/v-text-field&gt;
                &lt;/v-flex&gt;
                &lt;v-spacer&gt;&lt;/v-spacer&gt;
                &lt;v-flex xs5&gt;
                  &lt;v-text-field min="0" step="1" type="number" label="Episode" :value="track.episode"&gt;&lt;/v-text-field&gt;
                &lt;/v-flex&gt;
              &lt;/v-layout&gt;
            &lt;/v-card-actions&gt;
            &lt;v-card-actions&gt;
              &lt;v-spacer&gt;&lt;/v-spacer&gt;
              &lt;v-btn color="green darken-3" depressed @click="updateTrack({ title: track.title, season: 2, episode: 2})" class="mr-3"&gt;update&lt;/v-btn&gt;
              &lt;v-btn color="primary" depressed @click="deleteTrack(track.title)"&gt;delete&lt;/v-btn&gt;
            &lt;/v-card-actions&gt;
          &lt;/v-card&gt;
  </code></pre>
  
  <p>On place where it says season: 2 and episode: 2, that is the place where I want to pass values of text-fields.</p>
  
  <p>It is not working. It goes through my method and as result of <code>.then</code> it console log me that update was successful. I will provide updateTrack method:</p>
  
  <pre><code>updateTrack (payload) {
      db.collection('users').doc(this.userId).collection('tracker').doc(payload.title).update({
         season: payload.season,
         episode: payload.episode
      })
      .then(() =&gt; console.log('updated track'))
   }
  </code></pre>
  
  <p>If I change values in method or in template to simple values like 2 it works.</p>
