Your code works (did you try it) but there is no need to pass the (window) argument - your function/event isn't expecting an argument.

window['myevent']();

There is a more formal guide here at SitePoint which demonstrates using addEventListener with custom events, and using dispatchEvent to trigger the event on an element.

Note: IE 9 and below do not support the CustomEvent object. If you are using a JS Library, however, then most libraries support some form of custom event delegation.
