For some reason this is not doing anything, I think it may be the button

I am trying to make a webpage that when you put a number in the box, and press a button, it tells you if the number is even or odd in the console, but when I press submit, it doesn’t do anything.

This is my code, is there anything I should change or fix?
I thought it would tell me if it was even or odd but it didn’t do that.

const num = document.getElementById("numberText");
const result = document.getElementById("result");
const button = document.getElementById("submitBtn");

function isEven(number){
    if (number % 2 === 0) {
        return "this number is even";
    } else {
        return "this number is odd";
    }
}

if (button.clicked == true) {
    console.log(isEven(num));
}
