autocomplete email input

I have a standard email field in a popup, where users enter an email address. Some users have expressed shock and dismay, that the input does not remember prior email addresses that have been entered in the past. I imagine this may be by design and this post seems to explain it: http://stackoverflow.com/questions/19345879/input-autocomplete-on-does-not-work-with-chrome-is-it-a-… and this : http://stackoverflow.com/questions/8843424/input-field-value-is-not-added-to-field-history-when-the-… . Basically when I look in the console, I can see that there is no “form” element. There is just an “input” inside of a “div”. Therefore I can’t add “autocomplete=on” to the form element, if I add it to the input element by itself that doesn’t seem to work either. Is there a way for me to get the input to remember past email addresses? Here is a screenshot:
