I can't believe that this was still in there, but I needed to change
``` javascript
// Get the columnDisplayName's value
var columnValue = $(this).attr("value");
```
to
``` javascript
// Get the columnDisplayName's value
var columnValue = $(this).val();
```
``` javascript
// Get the columnDisplayName's value
var columnValue = $(this).attr("value");
```
to
``` javascript
// Get the columnDisplayName's value
var columnValue = $(this).val();
```
