Lazy load in Kendo UI treeview with caching

I am using Kendo UI TreeView to load hierarchical data in my webpage. By default, I am loading data upto 3 levels (ie Root -> Root directs -> Root directs' directs). I need a way to lazily load the remaining nodes as user expands further down the tree. Also, the already fetched data must be cached locally to avoid unnecessary calls for already expanded nodes. I am new to Kendo UI and do not have enough time to go through documentation. The json looks like

   {
      Id: '1',
      ParentId: '-1',
      Payload: {... }
      Children: [
          Id: '2',
          ParentId: '1',
          PayLoad: {...},
          Children: [{...}]
          ]
            ....
    }

Can someone point out to code samples ? How much of the above is supported out of box by Kendo ?

Thanks in advance.
