First : have you load the Plugin correct?

   dojo.require("dojox.grid.enhanced.plugins.Filter");

And maybe this helps you with your Problem:

UPDATE 1

Hi there! I have to dig a little into the width of the Web but lately i think i found the answer to your question how to define the filter.

 plugins: {
            filter: {
              isServerSide: true,
              setupFilterQuery: function(commands, request){
                if(commands.filter && commands.enable){
                     console.log(commands.filter);
                     request.query = {
                         "Name": "L*"
                                      }       
                }
               }
               itemsName:'songs',
               closeFilterbarButton: true,
               ruleCount: 8
              }
           }

I grab this from here: https://bitbucket.org/dojo/dojox/src/64328839903b/grid/tests/enhanced/test_enhanced_grid_filter.html

This example defines a filter that searches the store for all Names that begins with the letter "L". With the other supported Operators you can define your own filter.

Hope this helps you!
