title: monthSelected event emmiter in angular material datepicker
body: <p>I'm trying to accomplish a month only view of the <a href="https://material.angular.io/components/datepicker/overview" rel="nofollow noreferrer">angular material datepicker</a>.</p>
  
  <p>I saw this <a href="https://stackblitz.com/edit/angular-material2-year-picker?file=app%2Fcustom-datepicker%2Fmonth-picker-component%2Fmonth-picker.component.html" rel="nofollow noreferrer">datepicker</a> adapation from angular material datepicker, which does exactly what I'm trying to do. So I looked into the code and saw this (app/custom-datepicker/month-picker-component.html):</p>
  
  <pre><code>&lt;mat-datepicker #datepicker
              [touchUi]="touchUi"
              startView="multi-year"
              (yearSelected)="_yearSelectedHandler($event,datepicker)"
              (monthSelected)="_monthSelectedHandler($event,datepicker)"
              panelClass="month-picker"&gt;
  </code></pre>
  
  <p></p>
  
  <p>So I tried using the monthSelected in my code to check when the user selects a month, but it doesn't seem to actually fire any event, contrary to what happens in the <a href="https://stackblitz.com/edit/angular-material2-year-picker?file=app%2Fcustom-datepicker%2Fmonth-picker-component%2Fmonth-picker.component.html" rel="nofollow noreferrer">datepicker</a> I found where the author calls for datepicker.close() inside his custom _monthSelectedHandler function.</p>
  
  <p>My question is, was there some changes in the datepicker, am I doing something wrong, or is there a new way to do this? I tried searching and didn't find anything.</p>
