Kendo UI ASP.NET MVC Kendo Grid Edit Popup Globalization Validation Issue - asp.net-mvc

Question

i have a Kendo grid that uses an edit Popup. The culture in the client is de-DE, when an user tries to edit a decimal number i.e. 8,5 Kendo sends a null to the server for that value and returns validation message "The value 8.5 is not valid for 'PropertyName'". Any help will be greatly appreciated.
#{
var culture = System.Globalization.CultureInfo.CurrentCulture.ToString();
}
<script src="#Url.Content("~/Scripts/Kendo/cultures/kendo.culture." + culture + ".min.js")"></script>
jQuery.extend(jQuery.validator.methods, {
date: function (value, element) {
return this.optional(element) || kendo.parseDate(value) != null;
},
number: function (value, element) {
return this.optional(element) || kendo.parseFloat(value) != null;
}
});
<script type="text/javascript">
kendo.culture("#culture");
</script>
