Currently, Kendo Grid has a "column.values" option that accepts an array of key/value pairs.  These values are used to render human-readable text for fields that are foreign keys.  Depending on how the grid is used, this array of "available values" could be dynamic.  Currently, there is no way to update these arrays without calling "setOptions" manually with the new, correct column definitions.

To fix this, Kendo Grid should track changes to the "column.value" array (via some sort of observable or something - I'm not sure exactly how things work under the hood).  Alternatively, "column.values" could also accept a function.  This function would return the up-to-date values array (Kendo Grid would have to be smart enough to execute the function whenever necessary).

Note:  this is the same functionality that has been requested by http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/13355043-kendogrid-allow-updating-columns-values-array-nee
