Kendo Grid refreshing foreign key column data for cascading dropdown list

[Paul]

I have a column which creates a dropdown list from a foreign key value. 

I change the value in my application, the variable value changes but the drop down list does not update.

var dashboardTypeNames = [];
var menuNames = [];

columns: [              

              { field: "DashboardTypeId", values: dashboardTypeNames, title: "Dashboard Type" },
              { field: "MenuId", values: menuNames, title: "Menu" },              
        ],

On start I populate the dashboardTypeNames array with data using ajax the selected item value is then passed to another ajax which i want to populate the second dropdown I have an onchange function which gets the value of the selected item.

Anyhelp would be appreciated

Sorry I do get the correct data back and the variable has the new data but i cant refresh the dropdown with the new data.
