How to "copy" text from one div to another with JQuery?

I'm putting a player on my site. As I do not know much about JS / JQ, I got a simple template on the internet, I set up a layout and I set the script to my liking as far as I could.

Now I got stuck on something that I thought was super easy, but I've tried it in many ways without success. What I want is to "clone" the text that is in div (in this case the name of the song, from [currentIndex] ) to another div (in the player bar).

Here I am leaving the part of the script that I think has the possibility to do this so you better understand his logic. Look at my last attempt:

      Carousel.prototype.go_to = function( index, currentIndex )
    {   
if (currentIndex != index) {

    index = index%this.count;
    if (index < 0)
        index = index + this.count;

    this.$.faicha[currentIndex].classList.remove('ativo');
    this.$.faicha[index].classList.add('ativo');

    this.$.musica[0].setAttribute('src', 'som/' + index + '.mp3');

    /*Aqui abaixo minha tentativa*/
    this.$.nomedamusica[0].clone().appendTo(".nomedamusicaaqui");

    this.changeMusic();
    this.index = index;
}
};

.nomedamusica comes from the class where it has the name of the song. E .nomedamusicaaqui is the class of div where the text should be "pasted."

Just get the text of the active element with the class .ativa (music that is selected) and play within the other div , using:

'$(".nomedamusicaaqui").text($("div.ativa").text());'
            ↑                         ↑
       div destino         div de onde virá o texto

Example:

var Player = function ( $target )
{
	this.$ = {};
	this.$.body  	    = $target;
	this.$.prev 	 		= this.$.body.find('.prev');
	this.$.next 		    = this.$.body.find('.next');
	this.$.play 		    = this.$.body.find('.play');
	this.$.seek_bar			= this.$.body.find('.seek-bar');
	this.$.progress_bar		= this.$.body.find('.progress-bar');
	this.$.faichas 			= this.$.body.find('.faichas');
	this.$.music			= this.$.body.find('.music');
	this.$.faicha 			= this.$.faichas.find('.faicha');

	this.count = this.$.faicha.length;
	this.init_events();
};

Player.prototype.index = 0;
Player.prototype.count = 0;
Player.prototype.progress_ratio = 0;

Player.prototype.init_events = function (){
	var that = this;
	
	this.$.next.on('click', function(){
		that.next();
		return false;
	});
	this.$.prev.on('click', function(){
		that.prev();
		return false;
	});

	this.changeMusic();

	this.$.play.on('click', function(){
		play = !play;
		that.changeMusic();
		return false;
	});
	
	/* ação quando a música acabar */ 
	this.$.music.bind('ended', function(){
		that.next();
	});

	/**** barra de tempo ****/
	window.setInterval(function () {
		this.progress_ratio = that.$.music[0].currentTime / that.$.music[0].duration;
	    that.$.progress_bar.css({
		  transform: "scaleX(" + progress_ratio + ")"
		});
	}, 50);
	/* Permite alterar a hora atual da música */ 
	this.$.seek_bar.on('click', function (e) {
	        var x = e.clientX - that.$.seek_bar.offset().left,
	        ratio = x / that.$.seek_bar.width(),
	        time = ratio * that.$.music[0].duration;
	    that.$.music[0].currentTime = time;
	});
};

Player.prototype.next = function()
{
	this.go_to( this.index + 1, this.index);
};
Player.prototype.prev = function()
{
	this.go_to( this.index - 1, this.index);
};

Player.prototype.go_to = function( index, currentIndex )
{
   
	if (currentIndex != index) { // Evite recomeçar o áudio clicando na música atual

		index = index%this.count;
		if (index < 0)
			index = index + this.count;
		
		this.$.faicha[currentIndex].classList.remove('ativa');
		this.$.faicha[index].classList.add('ativa');
		/* mudar a fonte da música */
		this.$.music[0].setAttribute('src', 'http://audeficheux.com/projects/carousel/src/medias/' + index + '.mp3');
		
		this.changeMusic();
		this.index = index;

      // LINHA ADICIONADA
      $(".nomedamusicaaqui").text($("div.ativa").text());
	}
};

Player.prototype.changeMusic = function()
{	

	/* Tocar/pausar a música */ 	
	if (play == true) {
		this.$.play[0].classList.add('pausa');
		this.$.music[0].play();
      
      // LINHA ADICIONADA
   	$(".nomedamusicaaqui").text($("div.ativa").text());
   }
	else {
		this.$.play[0].classList.remove('pausa');
		this.$.music[0].pause();
	}
};
