Bind aggregation for panel?

Hi,

I am trying to bind json data to a panel .

I want to replace the header-text of the panel from the json data({title}).

{

    "data": [

        {

            "title": "XYZ"

        },

        {

            "title": "ABC"

        },

        {

            "title": "MVC"

        },

        {

            "title": "TVM"

        }

    ]

}

I tried to bind the above json into the panel header text as below,

var inputList=new sap.m.Panel({

    expandable : true,

  expanded : true,

  headerText : "{title}"

    });

    inputList.bindAggregation("headerToolbar","/data");  

But i am getting below error

Uncaught Error: Missing template or factory function for aggregation headerToolbar of Element sap.m.Panel#__panel0 !

Please help me to sort out the issue

Thanks,

Meera
