Check that your spelling of the attribute is correct, note the typo in the
example. Also, if you want to be extra-careful (just had to deal with this
yesterday) you can go all belt-and-suspenders on it:
parseInt( 0 + counter.data('maximum-length') )
The leading 0 + won't change the value, but it will force JavaScript to cast an
empty string to zero, so you don't get NaN (not a number), which may actually
be true, depending on how the parser does with the data-attribute.
