Make the checkbox behave with radiobutton

Make the checkbox behave like a radiobutton, allowing the checkbox to be deselected. And my select is also part and works the same as the checkbox if the value is greater than 0 the checkbox deselects, if you select a checkbox the select gets 0.

I have such a code in knockoutJS:

   var InternalAuditRecordTopic = function (data) {
                var self = this;
        self.InternalAuditRecordTopicID = ko.observable(data.InternalAuditRecordTopicID);
        self.InternalAuditRecordID = ko.observable(data.InternalAuditRecordID);
        self.Name = ko.observable(data.Name);
        self.Order = ko.observable(data.Order);
        self.Request = ko.observable(data.Request);
        self.NonComformityType = ko.observable(data.NonComformityType);
        self.Comformity = ko.observable(parseInt(data.Comformity));
        self.OM = ko.observable(parseInt(data.OM));
        self.Observation = ko.observable(data.Observation);
        self.Evidences = ko.observable(data.Evidences);          

        self.startPlaceHolders = function () {
            startPlaceHolders();
        };

    };


.....

        ko.cleanNode($("form#internalAuditRecordRegisterForm"));
        var viewModel = new InternalAuditRecord(@Html.Raw(Model.ToJson()));
        ko.applyBindings(viewModel, document.getElementById("internalAuditRecordRegisterForm"));

And in html:

section class="internalAuditRecordTopicDetail with-margin" data-
index="${$index}">
            <input type="hidden" name="InternalAuditRecordTopics[${$index}].Request" value="${Request}" />
            <input type="hidden" name="InternalAuditRecordTopics[${$index}].Name" value="${Name}" />

            <input type="hidden" name="InternalAuditRecordTopics[${$index}].OM" value="${OM}" />

            <input type="hidden" name="InternalAuditRecordTopics[${$index}].Order" value="${$index}" />
            <fieldset class="grey-bg relative internalAuditRecordTopic">

What I've already tried:

ko.bindingHandlers.isSelectedOM = {
                init: function (element, valueAccessor, allBindings, viewModel, bindingContext) {
                    if ($(element).is(':checked')) {
                        $(element).closest('table').find(':checkbox').prop('checked', false);
                    }
                },
                update: function (element, valueAccessor, allBindings, viewModel, bindingContext) {
                    if ($(element).is(':checked')) {
         $(element).closest('table').find(':checkbox').prop('checked', false);
                    $(element).closest('table').find('select').prop('value', 0);

                    }
                }
            };
