title: Restore collection values in a edited input text
body: <p>I have several text input that show the value in a collection, as:</p>
  
  <pre><code>&lt;input type="text" id="myval" value={{myvalue}}&gt;
  </code></pre>
  
  <p>I would like to have a <code>Reset</code> button that restore the original collection value, after the input text has benn edited. I tried with: </p>
  
  <pre><code>Router.render('mypage')
  </code></pre>
  
  <p>but it does not work.<br> I would like to solve this without adding a template helper for each input value.</p>
