Now when I click two times in a cell, it will be opened for editing.

+1 @IanGriffiths for diagonsing the Problem. As for a solution (or workaround rather), you can count the number of "pending" Edits. That means something like:

void BeginEdit()
{
    _numEdits++;
}

void CancelEdit()
{
    if(--_numEdits < 0)
        throw new Exception("WTF?"); 
}

void EndEdit()
{
    CancelEdit();
    if(_numEdits == 0)
        commitEdit();
}
