Select Checkbox !== Select Row Table

The select/unselect button works on the checkbox.

But it does not work for the row table.

//Select row table
$('#example').on('click', 'tr', function() {
  var $row = $(this),
    isSelected = $row.hasClass('selected')
  $row.toggleClass('selected')
    .find(':checkbox').prop('checked', !isSelected);
});

// Problem : Checkbox !== select row
$("#selectAll, #unselectAll").on("click", function() {
  var selectAll = this.id === 'selectAll';
  $("#example tr :checkbox").prop('checked', selectAll);
});

I think the checklist is just for display, for row selected and to mark it.

How when the select / unselect button is clicked,

it select on row table too, Not just on the checkbox?

Code Snippet Demonstration :

$('#example').dataTable();

//Select row table
$('#example').on('click', 'tr', function() {
  var $row = $(this),
    isSelected = $row.hasClass('selected')
  $row.toggleClass('selected')
    .find(':checkbox').prop('checked', !isSelected);
});

// Problem : Checkbox !== select row
$("#selectAll, #unselectAll").on("click", function() {
  var selectAll = this.id === 'selectAll';
  $("#example tr :checkbox").prop('checked', selectAll);
});
