i think you are missing a point here:

var checkBox_id = $(this).attr("id");
var $this = $('#' + checkBox);

The second line is is completly unnecessary. $this will refer to the same element as $(this). You just can do:

var $this = $(this);

for the same effect.

If you need the id of the tdand tr for the same thing, then you don't need it either.

var $td = $this.parent(); // Reference to td
var $tr = $td.parent(); // Reference to tr

Couple ways of doing it:

var row_id = $this.parent().parent().attr('id');
var row_id = $('#' + column_id).parent().attr('id');

You could use this i think

var row_id =   $this.closest('tr').attr('id')

There's no need to follow a chain of IDs - jQuery can find the closest enclosing table row for you:

$(".isActive").click(function() {
   var row_id = $(this).closest('tr').attr('id');
});
