onclick event on radio input is not triggering function

Question

I defined an element triggered on certain website and I attached onclick attribute to input elements created in this element. Now I'm trying to trigger the function by choosing either option but instead I'm getting error saying: "Uncaught ReferenceError: choosenFollowUp is not defined at HTMLInputElement.onclick"

Here is my code:

const choosenFollowUp = () => {
        console.log('choosenFollowUp triggered');
        let radios = document.getElementsByName('radioOption');

        for(let i=0; i<radios.length; i++){
            if(radios[i].checked){
                console.log(radios[i].value);
            }
        }
    }

    let radio = document.createElement('div');
    radio.style.width = '200px';
    radio.style.height = '65px';
    radio.style.backgroundColor = '#dddfe0';
    radio.style.border = '1px solid black';
    radio.style.borderTop = 'none';
    radio.style.borderBottomLeftRadius = '10px';
    radio.style.borderBottomRightRadius = '10px';
    radio.style.position = 'absolute';
    radio.style.top = '0px';
    radio.style.right = '250px';
    radio.innerHTML = `
       <p style="color: black; text-align: center; background-color: #FFA500; color: white; font-weight: 700;">Follow-Up Options</p>
       <div class="choosenOption" style="margin-left: 35px">
           <input type="radio" name="radioOption" value="30"> 30 min</input>
           <input type="radio" name="radioOption" value="60" checked="checked"> 60 min</input>
       </div>
    `

    const radioTrigger = () => {
        if(window.location.href === 'https://websiteAddress.com'){
            const radioParent = document.querySelector("#main-page-content");
            radioParent.appendChild(radio);
            const radioOption = document.getElementsByName('radioOption');

            for(let i=0; i<radioOption.length; i++){
                radioOption[i].setAttribute('onclick', "choosenFollowUp()");
            }
        }
    }
    radioTrigger();

1. I already tried to put onclick directly on input radios but the result is the same.
2. I cannot use JQuery.

Answer 1

Try

radioOption[i].addEventListener("click",choosenFollowUp);

or delegate:

const radioParent = document.querySelector("#main-page-content");
radioParent.addEventListener("click",function(e) {
  // here you can check e.target
})
