Populate <marquee> with dynamically created elements

Hey there! How's it going?

I'm using bar-ui for this project and since I am dynamically creating the list elements that are nested under the <ul class="sm2-playlist-bd> element your setTitle() function doesn't seem to populate the ‘marquee’ tag since it cannot find those ‘a’ tags. Any suggestions on how I can correct this issue? Thank you in advance.
