为什么ascensor.js插件不能工作?

我正在使用插件ascender .js，我试图做一个简单的例子，但它不起作用，我看不到错误。

JS

$(document).ready(function () {
    $('#ascensorBuilding').ascensor({
        ascensorName: 'ascensor',
        childType: 'section',
        ascensorFloorName: ['hello1', 'hello2', 'hello3', 'hello4'],
        time: 1000,
        windowsOn: 1,
        direction: "chocolate",
        ascensorMap: [
            [1, 0],
            [1, 1],
            [2, 1]
        ],
        easing: 'easeInOutQuad',
        keyNavigation: true,
        queued: false,
        queuedDirection: "y",
        overflow: "hidden"
    });
});

<button class="ascensor ascensorLink0">hello1</button>
<button class="ascensor ascensorLink1">hello2</button>
<button class="ascensor ascensorLink2">hello3</button>
<button class="ascensor ascensorLink3">hello4</button>
<div id="ascensorBuilding">
    <section>Hello1</section>
    <section>Hello2</section>
    <section>Hello3</section>
    <section>Hello4</section>
</div>

在结果中，我看到所有的部分在同一个页面中，当我点击按钮时没有发生任何事情…
