This is a Javascript question, and has nothing to do with Rails.

Nevertheless, I think you need to convert max_length to an integer. If
it is comming off whatever tag has id="counter" and
data-maximum-lenght="400", that is being pulled in as a String. Perhaps
try:

max_length = parseInt(counter.data('maximum-lenght'));
