How to set a component dataitem field to something other than a record field?

[Marc-QNX]

I have a component dataview, and I am trying to do something like this in the dataitem:

   dataMap: {
      getText: {
         setHtml: function() {
             return 'do some operations here';
         }
      },
   }

Is there any way to do something like this -- or any other way to set the value of a field to something other than a field of the record?
