title: How can I get information on element resize event in a Angular 2/Ionic 2 app?
body: <p>I need to get information about the size of an element when this element is resized in a Angular 2/Ionic 2 application.</p>
  
  <p>I Already know how to get initial size with ElementRef, but cannot find a way to get information about resizing.</p>
  
  <p>Note that I don't need the size of the window. I need the size of a element.</p>
