title: Updating store after initialization for AlpineJS doesn't work
body: <p>To initialize a store I have</p>
  <pre class="lang-js prettyprint-override"><code>document.addEventListener('alpine:init', () =&gt; {
    Alpine.store('selectedInput', 0)
  })
  </code></pre>
  <p>But when I do this in a function further down, it doesn't update <code>selectedInput</code>:</p>
  <pre class="lang-js prettyprint-override"><code>function example() {
    Alpine.store('selectedInput', 3)
  }
  </code></pre>
