When loaded as AMD module, it's triggered everywhere

[massic80]

Hi all,
I am working on a project based on requireJS and I'm trying to load NDIP only when a date input is present in page.
if(document.querySelector("input[type='date']")!==null) require(["libs/nodep-date-input-polyfill.dist"]);
The problem is: the polyfill is triggered whichever browser I use, duplicating the native behavior.
No problem if I hardcode the script in my page, prior the removal of ('function'==typeof define&&define.amd?define(b): which would trigger a requirejs error). Firefox would show the native interface, IE11 would show the polyfill.
Can you reproduce this problem?
