title: Triggering change detection manually in Angular
body: <p>I'm writing an Angular component that has a property <code>Mode(): string</code>.</p>
  
  <p>I would like to be able to set this property programmatically not in response to any event.</p>
  
  <p>The problem is that in the absence of a browser event, a template binding <code>{{Mode}}</code> doesn't update.</p>
  
  <p>Is there a way to trigger this change detection manually?</p>
