title: selectionChange does not emit for default option in mat-select - Angular Material
body: <p>I want to trigger a callback (or emit event) when <code>mat-select</code> is initialised with default value. Please see below template -</p>
  
  <pre><code>&lt;mat-form-field&gt;
            &lt;mat-select [(value)]="selectedSearchView"  (selectionChange)="onSelectionChange($event)" &gt;
              &lt;mat-option *ngFor="let view of searchViews; let i=index" [value]="view"&gt;
                {{view.name}}
              &lt;/mat-option&gt;
            &lt;/mat-select&gt;
  &lt;/mat-form-field&gt;
  </code></pre>
  
  <p>Is there a way to call <code>onSelectionChange($event)</code> when <code>mat-select</code> is initialised?</p>
