How to set default selected value of ion-option?
<p>I'm using Ionic v2 and I can not set the selected value when showing the page.</p>

<pre><code>&lt;ion-select [(ngModel)]="company.form"&gt;
    &lt;ion-option *ngFor="let form of forms" [value]="form" [selected]="true"&gt;{{form.name}}&lt;/ion-option&gt;
&lt;/ion-select&gt;
</code></pre>

<p>I've tried with <code>checked</code>, too but that isn't work either. How can I do this? </p>

<pre><code>Cordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.3
Ionic CLI Version: 2.1.13
Ionic App Lib Version: 2.1.7
Ionic App Scripts Version: 0.0.45
