Question

I have a table with multiple rows. If a user enters a value in an input in one of the cells, then I’d like the corresponding checkbox to be automatically selected.

I suspect that its something to do with the closest method that I am using.

Why don’t you just do parent().find()

$(document).ready(function(){        
    $('.this_payment').live('change keyup',function () {
        $(this).parent().find('.trans-selected').prop("checked", ($(this).val() > 0));
    });
});
