minggi on Filtering jsondata are slow -- eval

I have a filtering perfomance problem.

Now I fixed the problem with code below (replace the eval function):

Make this sense for you or have I an other problem with this code? It works much faster

        this.execute=function(){
           var match=_query, results=[];
           if(match === null){
               return self;
           }
           $.each(_data,function()
           {
               window.gridThis = this;
               if(new Function("return " + match.replace(/this/g, "window.gridThis") + ";")())
               {
                   results.push(this);
               }
           });
           _data=results;
           return self;
       };

Th original code was:

        this.execute=function(){
           var match=_query, results=[];
           if(match === null){
               return self;
           }
           $.each(_data,function(){
               if(eval(match)){results.push(this);}
           });
