title: this.$forceUpdate equivalent in Vue 3 - Composition API?
body: <p>In Vue 2, instance method <code>this.$forceUpdate()</code> could be used to update the component manually. How can we force update component in Vue 3 - Composition API (inside setup method) ?</p>
  <pre><code>setup(props, context) {
     const doSomething = () =&gt; {
       /* how to call $forceUpdate here? */
     }
  
     return {
         doSomething
     }
  }
  </code></pre>
  <p>Thanks, in advance.</p>
