title: Getting number of results of typeahead-input in meteor app
body: <p>I'm using typeahead with my meteor app using <code>sergeyt:typeahead</code>. I'm using multiple datasets:</p>
  
  <p><strong>helper</strong></p>
  
  <pre><code>  Template.demo.helpers({
      teams: function() {
        return [
          {
            name: 'nba-teams',
            valueKey: 'name',
            local: function() { return Nba.find().fetch(); },
            header: '&lt;h3 class="league-name"&gt;NBA Teams&lt;/h3&gt;',
            template: 'team'
          },
          {
            name: 'nhl-teams',
            valueKey: 'name',
            local: function() { return Nhl.find().fetch(); },
            header: '&lt;h3 class="league-name"&gt;NHL Teams&lt;/h3&gt;',
            template: 'team'
          }
        ];
      }
    });
  </code></pre>
  
  <p><strong>Result template:</strong></p>
  
  <pre><code>&lt;template name="team"&gt;
      &lt;h4&gt;&lt;i&gt;{{name}}&lt;/i&gt;&lt;/h4&gt;
  &lt;/template&gt;
  </code></pre>
  
  <p>Now I need to know e.g. for a submit-event of the form if there are results / how many results. But I don't find any informations how to do that.</p>
  
  <p>Maybe I have to iterate over the elements in <code>.tt-menu</code> but this feels quite bad for me.</p>
