YouTube Video API how to run after AJAX?

Question

YouTube

Hi all.
I made custom controls for YouTube video, everything works fine if the element with the video is already on the page when loading. I did it off the dock, but my implementation is similar to the example from this article https://css-tricks.com/play-button-youtube-and-vim...
The problem is that onYouTubeIframeAPIReady is launched as we add an API file to the page https://www.youtube.com/player_api but if my element with video is loaded by ajax then controls don't work because onYouTubeIframeAPIReady has already been executed. The question is how can such a problem be solved?
I tried to delete the file from the API after Ajax and add it again, but it did not help.
