title: access data context from keypress event
body: <p>Im  catching the keys pressed in a meteor app at the $("body") level. But inside the keypress callback I want to have access to the data context but I don't know how to get to it.</p>
  
  <pre><code>  Template.somename.rendered = function() {          
      $("body").keypress(function(e) {     
        e.stopImmediatePropagation();
  
        // change stuff on the data context
  </code></pre>
  
  <p>From the template i'm accessing the data context as {{this.data}}.</p>
  
  <p>Any ideas on how to go about it?
  Thank you in advance.</p>
