title: Can I access $data within a jquery call in an if-binding in Knockoutjs?
body: <p>I have a foreach binding and I want to display and item only if it is not already on the page, I seem unable to reference the current element within jquery</p>
  
  <pre><code>&lt;tbody data-bind="foreach: fixtures"&gt;
          &lt;tr&gt;
             &lt;!-- ko if: $("th:contains($data.date)").length == 0 --&gt;
             &lt;td data-bind="text: date"&gt;
             &lt;!-- /ko --&gt;
             &lt;/td&gt;
          &lt;/tr&gt;
  </code></pre>
