You forgot to add a name for your js function:

function functionName(event, value, caption) {
    $.ajax({
        type: 'GET',
        url: '/rating/update-rating',
        data: {
            points: value,
            post_id: $post - > id
        },
        success: function(res) {
            $(event.currentTarget).rating('update', res);
        },
        error: function(e) {
            console.log(e);
        }
    });
}
