title: Why reactive-table is empty?
body: <p>I have no luck to make reactive-table to work. Table is empty but data from collection is visible in browser console. </p>
  
  <p>Client side: </p>
  
  <pre><code>Template.devices.helpers({
      Devices : function(){
         return Devices;
      }
  });
  </code></pre>
  
  <p>Route: </p>
  
  <pre><code>Router.route('/devices', function(){
      Meteor.subscribe('devices');
      this.render('devices');
      this.layout("defaultLayout");
  });
  </code></pre>
  
  <p>Template:  </p>
  
  <pre><code>&lt;template name="devices"&gt;
     {{&gt; reactiveTable collection=Devices}}
  &lt;/template&gt;
  </code></pre>
  
  <p>Server side:</p>
  
  <pre><code>Meteor.publish('devices', function () {
          return Devices.find();
      });
  </code></pre>
  
  <p>What have I missed? </p>
