How to use a parameter function in the onclick attribute of Javascript?

Question

I’m starting to study JS and came across a problem. I’m following a tutorial to make an entire app lists, and when I tried to create a function to delete the whole I had a problem.

The function in question should carry a parameter related to the position of the whole within a vector and so it could erase it. I’m trying to do this using setAttribute with a hyperlink element (a), as I show in the code below.

function mostrarItens() {
  for (var item of itens) {
    var itemElement = document.createElement("li");
    var itemText = document.createTextNode(item);
    itemElement.appendChild(itemText);

    var linkElement = document.createElement("a");
    var pos = itens.indexOf(item);
    linkElement.setAttribute("onclick", "remover(" + pos + ");");
    var linkText = document.createTextNode("Remover");
    linkElement.appendChild(linkText);
    linkElement.style.marginLeft = "5px";
    linkElement.setAttribute("href", "#");
    itemElement.appendChild(linkElement);

    ulElement.appendChild(itemElement);
  }
}

function remover(pos) {
  itens.splice(pos, 1);
  mostrarItens();
}

Whenever I click on the link created to delete the whole I get an error saying that the remove function does not exist.

I would like to know what I am doing wrong. I have tried several things and so far nothing.

From now on, thank you very much.
