Select only one CheckBox from a group of child node in ASP.Net TreeView using jQuery

I'm new, I'm from Brazil - São Paulo! I would check one option, deselect the other options in each category

I am not able to do:

 $(function () {
        $("[id*=Tree] input[type=checkbox]").bind("click", function (a) {

            var parentDIV = $(this).closest("DIV");
            var isChecked = $(this).is(":checked");

            $("input[type=checkbox]", parentDIV).each(function () {
                $(this).removeAttr("checked");
            });

            $("input[type=checkbox]", parentDIV).prop("checked", this);

        });
    })

Please, help !!
