Turn checkbox into Yes or No & prevent text from disappearing

Hi, I used the solution at this post (https://datatables.net/forums/discussion/comment/121148/#Comment_121148) to update my dataTable to allow my checkboxes to show a Yes or No value when exporting to Excel. However, this solution also removes the text I have showing in those fields, I am showing an expiration date if the checkbox comes back true.

Can someone help me figure out how to keep the yes/no values, and also the text?

Here is my dataTable including Razor syntax:

<td role="gridcell">
        @Html.CheckBoxFor(modelItem => item.NotaryPublic, new { @id = "Notary Public-" + item.PID, @title = "Notary Public", @disabled = "disabled" })
        @if (item.NotaryPublic == true)
          {
             var npExpDate = string.Concat(string.Format(item.NotaryPublicExpirationDate.AsDateTime().ToString("MM-dd-yy")));
             var text = String.Concat(" (Exp Date: " + npExpDate + ")");
             @Html.DisplayFor(modelItem => text)
          }
     </td>

Or, if you prefer, here is the HTML:

<td role="gridcell">
        <input checked="checked" id="CPR Trained-929" name="item.CPRTrained" title="CPR Trained" type="checkbox" value="true" /><input name="item.CPRTrained" type="hidden" value="false" />
(Exp Date: 05-20-21)                                
    </td>

columnDefs: [
       { orderable: false, targets: 'no-sort' },
       {
           render: function (data, type, row) {
           var i = (type === 'export' ? ($(data).prop("checked") === true ? 'Yes' : 'No') : data);
               return i;
       },
       targets: [12, 13, 14, 15, 16]
       }
    ]
