I want to show a Sweet Alert 2 confirm message to user after submitting the form like this:

<form id="myForm" data-flag="0" action="" method="POST">
   @csrf
   <input type="checkbox" id="btn-submit" name="wallet_checked" onchange="this.form.submit();">
</form>

As you can see I have used onchange="this.form.submit();" to submit the form without using submit button and it works fine.

Then I tried adding this as script for showing SweetAlert message to user:

 $(document).on('click', '#btn-submit', function(e) {
    e.preventDefault();
    let form = $(this).parents('form');
    swal(
        {
        title: "Attention!",
        text: "Are you sure you want to make this",
        type: "warning",
        allowEscapeKey: false,
        allowOutsideClick: false,
        showCancelButton: true,
        confirmButtonColor: "#DD6B55",
        confirmButtonText: "Yes",
        cancelButtonText: "No",
        showLoaderOnConfirm: true,
        closeOnConfirm: false
    },

    function (isConfirm) {
        if (isConfirm) {
            console.log("YES");
        }
        return false;
    });
});

So the function shows Sweet Alert message on screen after clicking on the checkbox, but when I press on Yes button, it does not run console.log("YES");.

And this means that if (isConfirm) { at function (isConfirm) { is not working properly.

So how to solve this issue? What is wrong with isConfirm?
