oContainer refers to what in the example?

I was trying to run this example available in the Developer Guide;

oContainer.bindAggregation("content","/company/properties", function(sId, oContext){

  var value = oContext.getProperty("value");

   switch(typeof value){

   case"string":

   returnnew sap.ui.commons.TextField(sId,{

   value:{

   path:"value",

   type:new sap.ui.model.type.String();

   }

   });

   case"number":

   returnnew sap.ui.commons.TextField(sId,{

   value:{

   path:"value",

   type:new sap.ui.model.type.Float();

   }

   });

   case"boolean":

   returnnew sap.ui.commons.CheckBox(sId,{

   checked:{

   path:"value"

   }

   });

   }

});

What does oContainer refer to here?

I tried to instantiate FormContainer but that didnt work..

Please lhelp and let me know oContainer should be an instance of what?

Thanks alot
