Is it possible to give a submit input button the onsubmit attribute with javascript?

Question

Hello I've tried several things to give my submit button the onsubmit attribute. But I can't figure out, how to set onsubmit. Maybe you have an idea.

let btn = document.createElement('input');
            btn.value = "Delete";
            btn.name = "deleteButton";
            btn.type = "submit";
            btn.onsubmit="deleteCell();

let btn = document.createElement('input');
            btn.value = "Delete";
            btn.name = "deleteButton";
            btn.type = "button";
            btn.addEventListener('submit', deleteCell())

The "submit" event is for a form, not an input. You can use the "click" event on the input through:

const deleteCell = () => {
    console.log("hello World!")
};
let btn = document.createElement('input');
btn.value = "Delete";
btn.name = "deleteButton";
btn.type = "button";
btn.addEventListener('click', deleteCell);
