Grails UI datatable dynamic dropdownOptions

Question

Using the datatable, within the Grails UI plugin, does anyone know how to make the list of dropdownOptions dynamic?

You can specify the dropdownOptions like this:

[age:'Age', formatter:'number', editor:[type:'dropDown', controller:'demo', action:'tableChange', config:[dropdownOptions: ['Foo', 'Bar'], disableBtns:true]], sortable:true, resizeable: true],

I was hoping it would work in the following way:

[age:'Age', formatter:'number', editor:[type:'dropDown', controller:'demo', action:'tableChange', config:[dropdownOptions: Foo.list(), disableBtns:true]], sortable:true, resizeable: true],
