title: Trigger change event on ion-select component in ionic 5
body: <p>I am trying to trigger a change event everytime I change my option in an ion-select component. The problem is that the change event is triggered when I press the OK button in the popover of the ion-select button. I want to trigger the change event EVERYTIME I select an option.</p>
  <p>My initial goal is to select an option and close immediately the popover.</p>
  <p>P.S. Please do not propose interface property because I want to keep the design of ion-alert.</p>
  <p>Any ideas?</p>
  <p>My code:</p>
  <p>In my html file:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;ion-item&gt;
    &lt;ion-select value=&quot;-1&quot; (ionChange)=&quot;triggerEvent()&quot;&gt;
      &lt;ion-select-option value=&quot;-1&quot;&gt;All&lt;/ion-select-option&gt;
      &lt;ion-select-option value=&quot;a&quot;&gt;A&lt;/ion-select-option&gt;
      &lt;ion-select-option value=&quot;b&quot;&gt;B&lt;/ion-select-option&gt;
      &lt;ion-select-option value=&quot;c&quot;&gt;C&lt;/ion-select-option&gt;
    &lt;/ion-select&gt;
  &lt;/ion-item&gt;
  </code></pre>
  <p>In my ts file:</p>
  <pre class="lang-js prettyprint-override"><code>triggerEvent() {
      console.log('event trigger');
  }
  </code></pre>
