It is not getting in to the dataview because you do not display the data anywhere, you just store it somewhere in the memory. You can extend processOutput with:

this.domNode.innerHTML = this.val;

logger is defined in the client. You can use index-console.html to get the output, or use console.log() instead, (but do not forget to remove them after debugging).

problem solved by using apply Context

Extra function:

applyContext : function(context, callback)
{
        if (context && context.getTrackID()) 
        {
           this.contextobject = [context.getTrackID()];
         }
        callback && callback();
    },

and change guid : [dataobject.getGUID], --> guid : this.contextobject;

Hopefully i can help some with it.
