For this problem, I have finally put a new <i>
tag to refresh the select instead. Don't try to trigger an event if the selected option is the same that the one already selected.
If user click on the "refresh" button, I trigger the onchange event of my select with :
const refreshEquipeEl = document.getElementById("refreshEquipe1");
function onClickRefreshEquipe(event){
let event2 = new Event('change');
equipesSelectEl.dispatchEvent(event2);
}
refreshEquipeEl.onclick = onClickRefreshEquipe;
This way, I don't need to try select the same option in my select.
