title: How to change a button class on click in Vue?
body: <p>Currently i have this code which seems to work:</p>
  
  <pre><code>&lt;button class="initial" :class="{'is-active': activeTab === 1}" name="button"&gt;START&lt;/button&gt;
  </code></pre>
  
  <p>However when i click on the button, it doesn't apply the <code>is-active</code> class and remains the styled in initial class. Could anyone help?</p>
