title: Liferay 7 Theme : docment.ready() not fired when changing page
body: <p>I'm working on a liferay 7 theme and i've bound some JS on my main menu.
  All my js is in a document.rdy event.
  But what i can see is that when i change page, the document.ready() is not triggered, and all the js binding on my menu is lost.</p>
  
  <p>How can i do?</p>
