title: Check Ionic 2 Radio Button Programmatically using TypeScript
body: <p>Lets say I have the following list:</p>
  
  <pre><code>&lt;ion-list radio-group [(ngModel)]="autoManufacturers"&gt;
    &lt;ion-list-header&gt;
      Auto Manufacturers
    &lt;/ion-list-header&gt;
  
    &lt;ion-item&gt;
      &lt;ion-label&gt;Cord&lt;/ion-label&gt;
      &lt;ion-radio value="cord"&gt;&lt;/ion-radio&gt;
    &lt;/ion-item&gt;
  
    &lt;ion-item&gt;
      &lt;ion-label&gt;Duesenberg&lt;/ion-label&gt;
      &lt;ion-radio value="duesenberg"&gt;&lt;/ion-radio&gt;
    &lt;/ion-item&gt;
  
    &lt;ion-item&gt;
      &lt;ion-label&gt;Hudson&lt;/ion-label&gt;
      &lt;ion-radio value="hudson"&gt;&lt;/ion-radio&gt;
    &lt;/ion-item&gt;
  &lt;/ion-list&gt;
  </code></pre>
  
  <p>Depending upon what value I get from the database, I want to check the item in the list. Lets say if I get value 'cord' then item 2 should displayed as selected item. How can I achieve this using TypeScript?</p>
