Solve the following python programming problem given the following code:
def open(self, name, onsuccess, version = 1.0, onerror = None, onupgradeneeded = None) : 
    self._version = version 
    _result = self._indexedDB.open (name, version) 
    _success = EventListener ([self._onsuccess, onsuccess]) 
    _result.onsuccess = onsuccess.fire 
    _result.onupgradeneeded = onupgradeneeded 
    def onerror(e) : 
        print (('onerror: %s:%s' % (e.type, e.target.result))) 
def onblocked(e) : 
        print (('blocked: %s:%s' % (e.type, e.result))) 
_result.onerror = onerror 
    _result.onblocked = onblocked 

    
    

    Fix the buggy line: _result.onsuccess = onsuccess.fire
