Question

If I pass the data object to a function as in:

$("#someobject").data({
    "prp1":"x",
    "dosomething":function(){
    callthisfunction(this);  //<---- HERE the data ref is sent to a function
   }
});

...
function callthisfunction(in_data)
{
  //how is the data element?
  var theElementHoldingTheDataIs = in_data.????;  //<--- how can I get $("#someobject")


}

My questions is: is there a way from data to inform to which object it depends on or belong to?

You can use a closure:

var obj = $("#someobject");
obj.data({
    "prp1": "x",
    "dosomething": (function(scope) {
        return function() {
            callthisfunction(scope); //<---- HERE the data ref is sent to a function
        }
    })(obj)
});

Or if you just want to send the data object:

var obj = $("#someobject");
obj.data({
    "prp1": "x",
    "dosomething": (function(scope) {
        return function() {
            callthisfunction(scope.data());
        }
    })(obj)
});
