i change binding by collection length and working now.
bindings:[ { from:"collection.length", to:"$.clipNewest.model", transform:function(data){ console.log('transform data',this.collection); if(this.collection && this.collection.length>0 && this.collection.at(0)){ console.log('newest',this.collection.at(0)); return this.collection.at(0); } } }, ]
