jQuery Question

jQuery doesn't run on specific Wordpress page

I've got a Wordpress page and i'm running some jQuery to show and hide 2 input fields when someone clicks a checkbox. The problem is that this code runs perfectly on my Homepage but when i try to do the same thing (using the exact same html structure & jquery) on a subpage, it no longer works. It's not that the file doesn't get loaded because 1 part of the jQuery file runs fine on that page and I even have a console.log at the end of the file to show the file is fully loaded.

www.yogagids.nl is the homepage, when you click the checkbox "Evenementen" 2 datepicker fields show up, deselect it and they are hidden. Thats how it should work.

www.yogagids.nl/listings Is the page where this doesn't work. Same story, click the "evenementen" checkbox and the 2 datepicker fields should show and hide. However on this page nothing happens.

I'm really at a loss here, any and all help would be greatly appreciated.

Here is all the code that runs on this page, the actual file is larger but i couldn't post that many characters.

jQuery( document ).ready(function() {

//Create dummy input fields (altField) to show the user, this way the user sees a proper dateFormat while saving Unix Timestamp in the database.
//Do this for both the Add Listing page and the Search Fields

jQuery( "#event_date_end, #filter_event_date_end" ).after('<input type="text" class="input-text" name="event_date_end_dummy" id="event_date_end_dummy" placeholder="Einddatum"></input>');

//Define Dutch format and naming for the calendars, set the calendar to use unix date (easier to compare), set an alternative field to show the proper format.

I'm almost certain that the checkboxes HTML elements don't exist or are missing the corresponding value/classes when you are binding the change event. Try using the on method and also capture the event in the parent element, taking advantage of "event propagation":

     jQuery(".listingTypeSelect").on('change', 'input[value=event]', function() {
        console.log('clicked');
        if (!jQuery(this).is(':checked')) {

            jQuery('.search_event_date').css('display', 'none');
            jQuery(".listingTypeSelect input[value=studio]").prop('disabled', false);
            jQuery(".listingTypeSelect input[value=teacher]").prop('disabled', false);

            if (jQuery(window).width() > 992) {
               jQuery('.search_home_row_2 > div').css('width', '33.333%');
            } else {
                jQuery('.search_home_row_2 > div').css('width', '100%');
            }


        } else {

            jQuery('.search_event_date').css('display', 'inline-block');
            jQuery(".listingTypeSelect input[value=studio]").attr('checked', false); // Unchecks it
            jQuery(".listingTypeSelect input[value=teacher]").attr('checked', false); // Unchecks it
            jQuery(".listingTypeSelect input[value=studio]").prop('disabled', true);
            jQuery(".listingTypeSelect input[value=teacher]").prop('disabled', true);

            if (jQuery(window).width() > 992) {
                jQuery('.search_home_row_2 > div').css('width', '23.333%');
                jQuery('.search_home_row_2 .search_event_date').css('width', '30%');
            } else {
                jQuery('.search_home_row_2 > div').css('width', '100%');
                jQuery('.search_home_row_2 .search_event_date').css('width', '100%');
            }

        }
    });

It might be necessary to capture the event higher in the DOM. Example in search_jobs div.

jQuery(".search_jobs").on('change', '.listingTypeSelect input[value=event]', function() {
   //Code
});
