QML model link to JSON data -

how link json stream qml model angularjs?

in qml, have websocket object receives data server:

websocket {   id: socket   url: "ws://3.249.251.32:8080/jitu"   ontextmessagereceived: { var jsonobject = json.parse(message) }   onstatuschanged:      if (socket.status == websocket.error) { console.log("error: " + socket.errorstring) }      else if (socket.status == websocket.open) { console.log("socket open"); }      else if (socket.status == websocket.closed) { console.log("socket closed"); }   active: false } 

in json have like:

{ items: [ "foo", "bar" ] } 

then want display 2 tabs, on titles foo , other, unsurprisingly, titled bar.

this work great if create repeater goes through array in model , create tab each entry:

tabview {   anchors.fill: parent   repeater {     model: listmodel { id: tabs }     tab {       title: caption       rectangle { color: "red" }     }   } } 

up now, looks angularjs. need update model (scope angular) data received through websocket. this, have add tabs json listmodel such:

...   ontextmessagereceived: {      var jsonobject = json.parse(message)     tabs.append(jsonobject.itu.modalities);   } ... 

the problem is, each time i'll receive update json, tabs added. don't want clear listview each time, time consuming think. there smart way update model json smartly ? in angular, both javascript structure, easy merge. here, don't see easy way.
