title: How to reference a dom element in ember route?
body: <p>I was working on an EmberJS application developing.<br>
  I defined a route and a template for it</p>
  
  <p>And there is a little button, which id is <code>myBtn</code> in that template</p>
  
  <p>I wonder how and when i can reference that button in my <code>route.js</code></p>
  
  <p>If there is no way,i think i may wrote a single component and wrap it in that route(template),course,element reference in component is clearly and easily</p>
  
  <p>Hope there is a hint for me</p>
  
  <p>Thanks</p>
