Actually, checkboxes don’t exist in your dataset, so there’s nothing to apply the changes. You can check it in the log of your sample:

onClick:{
       index:function(){
         var table = this.getChildViews()[0];         
         table.eachRow(function(row){
           console.log(table.getItem(row));             
         });         
         $$('indextable').refresh();
         return false;
       }
      },

Here’s the correct snippet:
