Enable js on checkbox list ASP.NET Core

In my application ASP.NET Core I pass a Checkboxlist to my view.

In my view, I have made a javascript function to select all checkboxes and unselect all checkboxes.

When my checkboxes are selected I send the form. But in my controller, any checkbox is selected.

Thanks for your help.

Javascript function

function selectAllCompta() {
 var items = document.getElementsByName('myCheckBox');
 var cb = document.getElementById('cbSelectAll');
 var txt = document.getElementById('txtCb');

 if (cb.checked) {
    for (var i = 0; i < items.length; i++) {
        if (items[i].type == 'checkbox')
            items[i].checked = true;
    }
    txt.textContent = 'Déselectionner tout';
 }
 else {
    for (var i = 0; i < items.length; i++) {
        if (items[i].type == 'checkbox')
            items[i].checked = false;
    }
    txt.textContent = 'Sélectionner tout';
 }
}

View.cshtml

<input asp-for="CBC[i].Selected" name="myCheckBox" type="checkbox" class="form-control" />
