$.data doesn't work when hyphen is used

[nickngqs]

This will not work

div(data-animal-type='dragon')

$('div').data('animal-type'); // undefined

This will work

div(data-animaltype='dragon')

$('div').data(animaltype); // dragon

I think animal-type should work since we see alot of hyphens in HTML documents and is in the spec as well

Thanks @nickngqs, you're absolutely right. This has been fixed and released as v0.15.5.
