javascript - How can I get the value of a field in c# razor

I just want to check the value of a field in a jquery function. however the error says this field is not defined. Here is the field

                <div class="dx-field" id="Betragssumme">
                    <div class="dx-field-label">Betragssumme:</div>
                    <div class="dx-field-value mb-3">
                        @(Html.DevExtreme().NumberBox().ID("AufteilungSumme").Format(new JS("WaehrungsFormat")).ReadOnly(true).Placeholder("0,00") .OnValueChanged("CheckAwvMinBetragUeberschritten"))
                    </div>
                </div>

And here is the function:

function CheckAwvMinBetragUeberschritten(e) {
        var betragsSumme = document.getElementById("Betragssumme");

        if (betragsSumme.value > model.AwvMinBetrag) 
        {
            $("AwvCheckbox").hide();
        }
    }
