Trouble getting checkboxes to appear with javascript

Hi, I am trying to add checkboxes to one of my views using the javascript example depicted here: https://docs.knack.com/docs/javascript-jquery-examples#add-checkboxes-to-a-table

but for some reason, they never seem to appear?

My view is view 115, here is the code:

// Function that adds checkboxes

var addCheckboxes = function (view) {

// Add the checkbox to to the header to select/unselect all

$("#" + view.key + “.kn-table thead tr”).prepend(

'<th><input type="checkbox"></th>'

);

$("#" + view.key + “.kn-table thead input”).change(function () {

$("." + view.key + ".kn-table tbody tr input").each(function () {

  $(this).attr(

    "checked",

    $("#" + view.key + ".kn-table thead input").attr("checked") != undefined

  );

});

});

// Add a checkbox to each row in the table body

$("#" + view.key + “.kn-table tbody tr”).each(function () {

$(this).prepend('<td><input type="checkbox"></td>');

});

};

// Add checkboxes to a specific table view (view_1). Replace view_1 with your view key

$(document).on(“knack-view-render.view_115”, function (event, view) {

addCheckboxes(view);

});

// Cycle through selected checkboxes. Use this in any code that needs to get the checked IDs

$("#view_115 tbody input[type=checkbox]:checked").each(function () {

// add code here to get record id or row value

var id = $(this).closest(“tr”).attr(“id”); // record id

});

Not sure if there is more of this example that needs changing

Thanks for any potential help

Hey. Are you getting any Javascript errors in the console for the page that has that view in it? Is your ‘view_115’ a table with data in it?
