passing results from indexeddb to calling function

I have the following method that gets items form the object store:

self.getSpecificFromDB = function(a, b, c, callback) {
   self.trans = self.db.transaction(['do'], 'readonly');
   self.store = self.trans.objectStore('do');

    var items = [];

   var cursorRequest = self.store.openCursor();

    cursorRequest.onerror = function (event) {
            console.log("Cursor error");
    };
    cursorRequest.onsuccess = function (event) {
            var cursor = event.target.result;
                if (cursor) {
                    if (cursor.value.test == a) {
                        console.log("found it");
                        items.push(cursor.value);
                    }
                    cursor.continue();
                }

    };
  callback(items);
};

I would like to use the array returned in items in the calling method of my viewmodel:

        self.search = function() {
            console.log("search called");
            var resultarray = self.dbinstance.getSpecificFromDB(self.t(), self.d(), self.g(), function(elem) { console.log(elem);});
            console.log(resultarray);
            if (resultarray != undefined && resultarray.length > 0) {
                self.searchitems.push({
                  general: resultarray[0].test,
                  two: resultarray[0].test2,
                  three: resultarray[0].test3
                });
            } else {
                self.errormessagediv("Nothing was found");
            }
        };

The callback itself works, but the resultarray is always undefined, even when I use something like function (item) { return item; } as a callback. How do I get the results to my viewmodel?
