title: KoGrid update cell
body: <p>I am trying to update a single cell with KoGrid, but I don't see the update happen until I sort the grid by clicking on the column header.</p>
  
  <p>The following is the code I'm using. JSFiddle available here: <a href="http://jsfiddle.net/b22Ex/2/" rel="nofollow noreferrer">http://jsfiddle.net/b22Ex/2/</a></p>
  
  <p>The line that's not working is: vm.data()[0].b(100). Shouldn't that work since the value is a ko.observable?</p>
  
  <pre>
  <code>
      var L = [
          {a:ko.observable('a1'), b:ko.observable('b1'), c:ko.observable('c1')},
          {a:ko.observable('a2'), b:ko.observable('b2'), c:ko.observable('c2')},
          {a:ko.observable('a3'), b:ko.observable('b3'), c:ko.observable('c3')}
      ];
      var vm = {
          data: ko.observableArray(L)
      };
      window.vm = vm;
      ko.applyBindings(vm);
      vm.data()[0].b(100)
      console.log("DONE CHANGING VALUE");
  
  </code>
  </pre>
  
  <p>By the way, I also came across <a href="https://stackoverflow.com/questions/15642798/kogrid-how-to-refresh-grid-in-case-data-is-changed">KoGrid how to refresh grid in case data is changed</a>
  but I don't want to update the entire dataset.</p>
