//component
import { ScriptService } from '../services/script.service';
constructor(private script: ScriptService) {
}
ngOnInit() {
this.script.load('calenderly').then(data => {
console.log('script loaded ', data);
}).catch(error => console.log(error));
}I tried integrating calenderly in one component which actually worked when i visit the page for the first time but when I revisit the page from other page (route) it doesn't works.

script.onreadystatechange = null;
this.scripts[name].loaded = true;
resolve({script: name, loaded: true, status: 'Loaded'});

<div class="calendly-inline-widget" data-url="https://calendly.com/prince-shah97/15min" style="min-width:320px;height:630px;"></div>
<!-- Calendly inline widget end -->strong textI have added dynamic js to my controller using the reference from medium "https://medium.com/better-programming/angular-load-external-javascript-file-dynamically-3d14dde815cb". It worked but only when I refresh the same page but not when I go the the page from the other route(page).
