The input does not work on the phone, but on the computer it works, what should I do?

Question

JavaScript

$(".cart-info__promo").on("keyup", (function () {
        var t;
        if (t = $(this).val(), $.ajax({
                type: "GET",
                url: "../db/promo.php",
                data: {
                        promocode: t
                },
                async: !1,
                dataType: "json",
                success: function (t) {
                        s = t
                }
        }), "true" == s.isCorect) {
                if (o.isPromo) return;
                $(".cart-info__price-price").addClass("promo-done"),
                o.promo = o.price * (1 - s.procent / 100),
                $(".cart-info__price-promo").text(`$ {
                        o.promo
                }
                $ {
                        o.currency
                }`),
                o.isPromo = !0
        } else $(".cart-info__price-price").removeClass("promo-done"),
        $(".cart-info__price-promo").text(""),
        o.isPromo = !1
}))

Unfortunately, I minimized the code and did not save the old file, but that's not the point. For some reason it does not work on mobile phones, but everything works on desktop

keyup event doesn't work on mobile, add input:

$(".cart-info__promo").on("keyup input", (function () {
        var t;
        if (t = $(this).val(), $.ajax({
                type: "GET",
                url: "../db/promo.php",
                data: {
                        promocode: t
                },
                async: !1,
                dataType: "json",
                success: function (t) {
                        s = t
                }
        }), "true" == s.isCorect) {
                if (o.isPromo) return;
                $(".cart-info__price-price").addClass("promo-done"),
                o.promo = o.price * (1 - s.procent / 100),
                $(".cart-info__price-promo").text(`$ {
                        o.promo
                }
                $ {
                        o.currency
                }`),
                o.isPromo = !0
        } else $(".cart-info__price-price").removeClass("promo-done"),
        $(".cart-info__price-promo").text(""),
        o.isPromo = !1
}))
