How to toggle the checkbox while the user clicks on the row where the checkbox resides in?

I have a table with 2 columns, the first column shows the text, and the other column has a checkbox.

The code is as follows, and the checkboxes are generaged by JavaScript, e.g. var checkbox = document.createElement("input");

<script type="text/javascript">
      function create_table() {
       var data = ["Sandwidch", "Hamburger", "Bacon"];
       var table = document.getElementById("menu");
       for (var option in data) {
          var row = table.insertRow(-1);
          var cell1 = row.insertCell(0);
          cell1.innerHTML = data[option];

          var cell2 = row.insertCell(1);
          var checkbox = document.createElement("input");
          checkbox.type = "checkbox";
          checkbox.name = "choiceCbx";
          cell2.appendChild(checkbox);
        }
      }
      window.onload = create_table;
</script>

<body>
    <table id="menu">
        <tr>
           <th>Food</th>
           <th>Choice</th>
        </tr>
    </table>
</body>

When the user clicks on one of the rows in the table, if the checkbox on the row was checked, it should become unchecked, and vice versa.

I used the following code to toggle the checkbox but in vain, it seems just detects the "TH" row, but not the "TR" rows:

$(document).ready(function() {
  $('#menu tr').click(function(event) {
    if (event.target.type !== 'checkbox') {
      $(':checkbox', this).trigger('click');
    }
  });
});

How should I modify my code to make the toggle function work?

Try this. Also you might want to add more details to your question because the HTML does not contain any checkboxes

you can do that...

const table_foods = document.querySelector('#records tbody')

table_foods.onclick=e=>
  {
  if (e.target.matches('input[type=checkbox]')) return  // to not disturb  natural check action
  let chkBx = e.target.closest('tr').querySelector('input[type=checkbox]')
  chkBx.checked = !chkBx.checked  
  }
 /* cosmetic part */

table {
  border-collapse: collapse;
  margin-top: 25px;
  font-family: Arial, Helvetica, sans-serif;
  font-size: 14px;
  } 
thead {
  background-color: aquamarine;
  }
tbody {
  background-color: #b4c5d8;
}
td, th {
  border: 1px solid grey;
  padding: .3em .7em;
}
<table id="records" class="content">
  <thead>
    <tr> <th>Food</th> <th>Choice</th> </tr>
  </thead>
  <tbody>
    <tr>
      <td>Sandwitch</td>
      <td><input type="checkbox" name="answerCbx-1" /></td>
    </tr>
    <tr>
      <td>pizza</td>
      <td><input type="checkbox" name="answerCbx-2" /></td>
    </tr>
  </tbody>
</table>
