The Wrong Way I have a Web Component which looks like this: 1 <x-radial-buttons id="radial-button-template"></x-radial-buttons> If I try to access it by its ID…. 1 2 var temp = document.querySelector("#radial-button-template"); // returns <x-radial-buttons id=”radial-button-template”></x-radial-buttons> But I cannot access any of the function it. They return “undefined”. So if I tried this: 1 2 var temp = document.querySelector("#radial-button-template"); temp.getFirstElement // returns undefined Why is This Happening?
