Knockoutjs foreach if inside table

I have a foreach creating a table in one of my pages. My goal is when they checked the checkbox, I would add additional items for this table

My problem is that when the table is first drawn everything works as expected. But if I check the box after drawing the table, the ko if statement does not over-evaluate. What is the best method to achieve this goal? My current code is below.

<tbody data-bind="foreach: AvailableCerts">
    <tr>
        <td>
            <label class="label-checkbox inline">
                <input type="checkbox" data-bind="value: Id, checked: IsSelected">
                <span class="custom-checkbox"></span>
                <span data-bind="text:Name"></span>
            </label>

        </td>
        <td data-bind="text:CertifyingBody"></td>
        <td>
            <!-- ko if: (IsSelected) -->
            <input data-bind="value : EntryDate" required type="date" class="form-control input-sm">
            <!-- /ko -->
        </td>
        <td>
            <!-- ko if: ExitDateRequired -->
            <input data-bind="value : ExitDate" required type="date" class="form-control input-sm">
            <!-- /ko -->
        </td>
        <td>
            <!-- ko if: CaseNumberRequired -->
            <input data-bind="value : CaseNumber" required type="text" class="form-control input-sm">
            <!-- /ko -->
        </td>
    </tr>
</tbody>

      

        
        
        
      

    

And my viewModel

 function AppViewModel() {
    var self = this;

    self.rootUrl = window.location.protocol + "//" + window.location.host + "/Certs/";
    self.AvailableCerts = ko.observableArray([]);

    self.getAvailableCerts = function () {
        $.ajax({
            url: self.rootUrl + "AvailableCerts",
            type: "GET",
            cache: false,
            dataType: "json",
            success: function (results) {
                if (results != null) {
                    self.AvailableCerts(results);
                } else {
                    self.AvailableCerts([]);
                }
            }
        });
    };

    self.getAvailableCerts();
}

ko.applyBindings(new AppViewModel());
