WTemplate::renderTemplate() does render the widgets bound to the WTemplate into the given stream as html. This is done using WWidget::htmlText(), which also make the application execute the JavaScript necessary for the widget to function correctly.

This is an issue, because WTemplate::renderTemplate() does not require or make the WTemplate part of the DOM tree. This can lead to JavaScript being called on DOM elements that do not exists on the client side, leading to errors.
