title: jqGrid default checked checkboxes
body: <p>I made subgrid and want that be checkboxes were checked by default.</p>
  
  <pre><code>colModel: [
          {
              name: 'enb', index: 'enb', width: 60, align: 'center', editable: true,
              formatter: 'checkbox', editoptions: { value: 'Yes:No', defaultValue 'Yes' },
              formatoptions: { disabled: false }
          }]
  </code></pre>
  
  <p>But for some reason this does not occur. I use jqGrid 4.4.4 version. 
  What i do wrong?</p>
