title: ObjectlistView Checkbox Issue
body: <p>I have an issue trying to get a Checkbox working with <code>ObjectListview</code>. </p>
  
  <p>My model looks like this:</p>
  
  <pre><code>public class object
  {   
      public string name {get; set;}
      public int age {get; set;}
      public bool inuse {get; set;}
  }
  </code></pre>
  
  <p>And I added a <code>FastObjectListView</code> via the Designer in Visual Studio to a Win Forms Application. 
  Then, I added the Columns and set the <code>AspectName</code> for each column to the Models Property (First column: AspectName: name, Second Column: AspectName: age, Third Column: AspectName: inuse).</p>
  
  <p>Afterwards, I filled the <code>ListView</code> with this:</p>
  
  <pre><code>using (var context = new objectDb())
  {
      var objectlist = context.objects.ToList();
      fastoLV_Clean.SetObjects(objectlist);                             
      fastoLV_Clean.Refresh();
  }       
  </code></pre>
  
  <p>That works, and I can see my Database entries in the <code>ListView</code>. </p>
  
  <p>Now I want to add a CheckBox column where someone can check or uncheck the items to delete them and I can not get the checkbox to work. </p>
  
  <p>I have added a Column and set <code>CheckBox</code> to true, changed the <code>CheckedAspectName</code> of the <code>ListView</code> and now I can see the Checkboxes but nothing happens if I click them to check. 
  I think I'm on the completely wrong track, what do I have to do to make it work?</p>
  
  <p>Thank you very much!!</p>
