title: Angular slickgrid edit handler does not trigger on selecting same value from dropdown
body: <p>I have a requirement in angular slickgrid where I want to edit the row with the same option which in result will update the date on which the update was made.</p>
  <p>What I actually do is call an API on edit command handler when any changes are made in the table, but when I click on the same option from dropdown, the handler is not triggered(which is valid as there was no change made, but for my purpose I need that to be triggered)</p>
  <p>So my code looks something like this:</p>
  <p>These are my grid options</p>
  <pre><code>{
              enableAutoResize: true,
              enableSorting: true,
              editable: true,
              autoEdit: true,
              autoCommitEdit: true,
              editCommandHandler : (item, column, editCommand) =&gt; EditHandler(item, column, editCommand)//This is my EditHandler method which gets triggered and calls an API in backend
  }
  </code></pre>
  <p>This is my column definition</p>
  <pre><code>{
      id: 'status', name: 'Status', field: 'status', 
      filterable: true,
      editor: {
        collection: [{ value: 'progress', label: 'Progress' }, { value: 'new', label: 'New' }, { value: 'done', label: 'Done' }],
        model: Editors.singleSelect
      }
    }
  </code></pre>
  <p>Now suppose If a row contains <em>Progress</em> in the status column and when I change that to <em>New</em> from dropdown my <em>EditHandler</em> method triggers and I proceed with my changes.</p>
  <p>But what I want is to <strong>click on Progress again</strong> and want to trigger the <strong>EditHandler</strong> method and call the API which updates the date with the same status</p>
