Ext 4.2 Using proxy to save tree

Question

when I use insertChild() or Sync(), proxy sends GET to server with just _dc param, what I should do to save my tree via proxy?

Configure a writer inside the proxy. Without the writer proxy does not know what to do.

I have a tree in Ext 5.0 (but it works also in Ext 4.x) with tree model configured this way:

Ext.define('At.model.ContinentModel',{
     extend:'Ext.data.TreeModel'
    ,alias:'model.continentmodel'
    ,idProperty:'id'
    ,fields:[
         {name:'text', type:'string', persist:true}
        ,{name:'iconColor', type:'string'}
    ]
    ,proxy:{
         type:'ajax'
        ,url:'resources/service.php/tree/read/1/'
        ,writer:{
             type:'json'
            ,allowSingle:false
            ,encode:true
            ,rootProperty:'data'
        }
    }
});

The tree store is configured with autoSync:true. Changes in text field trigger server requests that look like this:
