title: Autogenerated id on view emberjs
body: <p>Hi i´m new at Embers and at stackoverflow. I´ve been working on this issue for a week. I´m trying to make an editable table with embers but the main problem is to autogenerate an id for my hidden TextFields. Inside my handlebar-template I´m generating this kind of textfields:</p>
  
  <pre><code>{{view Ember.TextField id="first_input_" class="hidden"}}
  </code></pre>
  
  <p>But I want to call a HandlebarsHelper who would give me a number for that row, something like this:</p>
  
  <pre><code>{{view Ember.TextField id="first_input_"{{{getId}}}  class="hidden"}}
  </code></pre>
  
  <p>Being my Handlebars Helper something like this:</p>
  
  <pre><code>Handlebars.registerHelper('getId', function() {
      id = id + 1;
      return new Handlebars.SafeString(id);
  });
  </code></pre>
  
  <p>I hope someone can help me with this, i thougth about not using Ember.TextField and just a normal imput but it could be easier to have it with ember for binding sake.</p>
  
  <p>Thank you.</p>
