title: Angular Material mat-radio-button does not change selection
body: <p>I use mat-radio-button in material table and it is displayed properly at the beginning of each row.</p>
  <p>However, when I click another option, the previous selections still remains selected.</p>
  <p>So, how can I unselect them after selecting another one?</p>
  <pre class="lang-html prettyprint-override"><code>&lt;ng-container matColumnDef=&quot;radio&quot;&gt;
      &lt;th mat-header-cell *matHeaderCellDef&gt;&lt;/th&gt;
      &lt;td mat-cell *matCellDef=&quot;let row&quot;&gt;
        &lt;mat-radio-group&gt;
          &lt;mat-radio-button (click)=&quot;radioSelected(row)&quot; [value]=&quot;row&quot;&gt;
          &lt;/mat-radio-button&gt;
        &lt;/mat-radio-group&gt;
      &lt;/td&gt;
  &lt;/ng-container&gt;
  </code></pre>
