I have a checkbox for each row within a kendo grid. If the user sorts or filters the grid, the checkmarks are cleared from the checkboxes. How can I prevent the checkboxes from unchecking or re-check them after the sort or filter occurs? Please refer to the following js fiddle to observe the behavior during sorting:

<http://jsfiddle.net/e6shF/33/>

Here's the code on the jsfiddle for reference (...needed to ask this question):

```
$('#grid').kendoGrid({
    dataSource: { data: [{id:3, test:'row check box will unchecked upon sorting'}]},
    sortable: true,
    columns:[
{
    field:'<input id="masterCheck" class="check" type="checkbox" /><label for="masterCheck"></label>', 
    template: '<input id="${id}" type="checkbox" />',
    filterable: false,
    width: 33,
    sortable: false // may want to make this sortable later. will need to build a custom sorter.
},
    {field: 'test',
     sortable: true}
]});

```
