I'm using jQGrid 3.1.8 with jQuery 1.4.3. I have a grid that has two columns in it that are set up as checkboxes, like so:

{name:'inv',index:'inv', width:20, sortable: false, search: true, editable: true, formatter:'checkbox', formatoptions: {disabled : false}, edittype: 'checkbox', editoptions:{size:4,value:"on:off"}}

This produces the desired checkbox element in the HTML. However, when looking at the raw HTML, the element lacks the ID and NAME attributes I expect per this page:
