UITextView (in UITableViewCell) jumps to top instead of scrolling to location

I have a UITextView in a custom UITableView. I'm trying to make the height dynamically size itself, and scroll to the correct location (cursors location).

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    if ([text isEqualToString:@"\n"])
    {
        NSRange cursor = NSMakeRange(range.location + 1, 0);

        NSMutableString *mutableT = [NSMutableString stringWithString:textView.text];
        [mutableT insertString:@"\n " atIndex:range.location];
        [textView setText:mutableT];

        [textView setSelectedRange:cursor];
        [textView sizeToFit];
        [textView layoutIfNeeded];

        [self.myTableView beginUpdates];
        [self.myTableView endUpdates];
        return NO;
    }
    return YES;
}

First:, when the text has to go to the next line, without the user enter a new line (word wrap), then this whole code doesn't work.

Second: When the user enters a new line, and it gets out of view, the tableView gets scrolled to the top. Then when I enter another char, it gets back to normal.
