title: How to modify KendoUI DropDownList items
body: <p>We used the Kendo UI DropDownList the first time without binding with knockout.
  Via jquery a usual html input is transformed into a KendoUI DropDownList.
  But how can i remove/edit/add items to the options?</p>
  
  <p>If i modify the html inputs options via jquery it has no influence on the kendoui dropdown - even with a refresh call afterwards.</p>
  
  <p>Any ideas how to do this?
  Thanks</p>
