title: Why is $event binding not working on RowGroup tables using PrimeNG?
body: <p>I'm using RowGroup to store 3 different tables and that works great, but my issue is that the <strong>onRowSelect</strong> function doesn't work at all and because of that when I click on any row of the RowGroup tables, nothing happens.</p>
  
  <p>I also have an external table called <strong>"MY TABLE"</strong> that if you click on any of the row you will get a pop-up with the row info in it. That's the exact functionality I want for my RowGroup tables but I can't get it to work.</p>
  
  <p>Here's my working code: <a href="https://plnkr.co/edit/cjHzNQk8z50EQtwi9Zzz?p=preview" rel="nofollow noreferrer"><strong>PLUNKER</strong></a></p>
  
  <pre><code>&lt;p-dataTable [value]="data" sortField="room" rowGroupMode="subheader" groupField="room" expandableRowGroups="true"
      [sortableRowGroup]="false" [expandedRowsGroups]="expandedGroups"&gt;
    &lt;ng-template pTemplate="rowgroupheader" let-rowData&gt;{{rowData.room}} - INFO&lt;/ng-template&gt;
  &lt;p-column field="status" header="ID"&gt;&lt;/p-column&gt;
  &lt;p-column field="name" header="Title"&gt;&lt;/p-column&gt;
  &lt;/p-dataTable&gt;
  </code></pre>
