I am creating the mobile version on a current Rails app with a "quiz" feature. There is currently a count of how many questions you have answered being generated by this function.

```
function updateGroupProgressCounter($group){
 var count = $group.find('tr').has('input:checked').length;
 $group.parents('.carousel').find('.checkedCount').text( count);
}

```

I am changing the inputs from radio buttons to select boxes for mobile and want to keep the count feature but can't quite make it work so far. I've tried 

```
var count = $group.find('tr').has('select option:selected').length;

```

but gives me the total number of questions in that group. Any help is appreciated.
