要素が表示されたらカウントアップを開始する様にodometer.jsを編集したいです。
以下のコードにて現状は画面がリロードされるとカウントが開始されます。

上記コードのどこが原因で画面リロード時にscriptが実行されているのでしょうか？
要素取得してDOMをいじるコード（以下）は動いたのですが、カウントは画面リロード時にスタートされてしまいます。
```javascript
$(function() {
// 引き金となる要素を設定
let triggerNode = $(".odometer ");
// 画面スクロール毎に判定を行う
$(window).scroll(function(){
// 引き金となる要素の位置を取得
let triggerNodePosition = $(triggerNode).offset().top;
// 現在のスクロール位置が引き金要素の位置より下にあれば‥
if ($(window).scrollTop() > triggerNodePosition - 200) {
// 動かすJSの指示
$('.odometer-inside').html();
$("p").css("color","#ff4500");
}
});
});
