Amplitude.js и Ajax

Как работать с Amplitude.js через Ajax? Если страница загружена динамически, то инициализация не происходит.

Amplitude.init({
  songs: [
    {
      "name": "Risin' High (feat Raashan Ahmad)",
      "artist": "Ancient Astronauts",
      "album": "We Are to Answer",
      "url": "../songs/Ancient Astronauts - Risin' High (feat Raashan Ahmad).mp3",
      "cover_art_url": "../album-art/we-are-to-answer.jpg"
    },
    {
      "name": "The Gun",
      "artist": "Lorn",
      "album": "Ask The Dust",
      "url": "../songs/08 The Gun.mp3",
      "cover_art_url": "../album-art/ask-the-dust.jpg",
    },
  ],
});
