This appears very simple but I cannot see why it's not working. The selector is correct however the div `.faqContent` is simply not being updated with the `data-height` attribute.

```
$('.faqItem .faqContent').each(function(){
    var h = $(this).height();
    $(this).data('height',h);
});

```

I have checked that `var h` is correct, it is in colsole.log as correctly holding the height. 

**EDIT**
It's absolutely not conflict, and console shows no errors.
