title: Getting td value returns undefined
body: <p>I am trying to access the td value of a row above a context. I am able to get the row above with the <code>prev()</code> method and also get the children with the <code>children()</code> method, but when I append a find() with a selector onto that, I am unable to find the particular cell I am looking for. </p>
  
  <p>When I log the return from <code>children()</code> I see all the table data i have in there. </p>
  
  <p>Why cant I find by id? See code below.</p>
  
  <pre><code>$("#tblProducts tbody").on("click", "#btnSubmitUpdate", function (e) {
      var btnSaveUpdate = $(this);
  
      var tr = btnSaveUpdate.closest("tr");
  
      var trAbove = $(tr.prev()[0]);
      var desc = trAbove.children().find("#tdDescription").val();
  
      //desc is returning undefined
      console.log(desc);
  });
  </code></pre>
