Bootstrap Carousel miért nem indul el?

Itt próbálom részletezni a problémámat. Szabályosan bt oldaláról vettel le a Carousel-t, csatoltam hozzá bt-4 js-t is:

Kód:

<div id="myCarousel" class="carousel slide" data-ride="carousel">

<!-- Indicators -->

<ol class="carousel-indicators">

<li data-target="#myCarousel" data-slide-to="0" class="active"></li>

<li data-target="#myCarousel" data-slide-to="1"></li>

<li data-target="#myCarousel" data-slide-to="2"></li>

</ol>

<!-- Wrapper for slides -->

<div class="carousel-inner" role="listbox">

<div class="item active">

<img class="d-block img-fluid" src="bootstrap-3.3.7-dist/img/slider/Cherry_slider.jpg" alt="Los Angeles">

</div>

<div class="item">

<img class="d-block img-fluid" src="bootstrap-3.3.7-dist/img/slider/nevjegy_slider.jpg" alt="Chicago">

</div>

<div class="item">

<img class="d-block img-fluid" src="bootstrap-3.3.7-dist/img/slider/Budapest_slider.jpg" alt="New York">

</div>

</div>

<!-- Left and right controls -->

<a class="left carousel-control" href="#myCarousel" data-slide="prev">

<span class="glyphicon glyphicon-chevron-left"></span>

<span class="sr-only">Előző</span>

</a>

<a class="right carousel-control" href="#myCarousel" data-slide="next">

<span class="glyphicon glyphicon-chevron-right"></span>

<span class="sr-only">Következő</span>

</a>

</div>

Js:

$('#myCarousel').carousel({

/*

default = 5000

milisec / false,

*/

interval: 3000,

/*

default = true

true / false

*/

keyboard: true

})

De nem akar elindulni... Tud valaki segíteni, miért nem?
