Finally for having customized background image for the UIBarButtonItem and to accomodate the alignment, I have abandon UIBarButtonItem and adding UIButton manually.

UIImage *buttonImage = [[UIImage imageNamed:@"button.png"] stretchableImageWithLeftCapWidth:10 topCapHeight:0];
UIButton *btnTest = [UIButton buttonWithType:UIButtonTypeCustom];
[btnTest setBackgroundImage:buttonImage forState:UIControlStateNormal];
[btnTest setTitle:@"Back" forState:UIControlStateNormal];   
[btnTest.titleLabel setFont:[UIFont boldSystemFontOfSize:13]];  
[btnTest setBackgroundImage:[imgToolbarButton stretchableImageWithLeftCapWidth:5 topCapHeight:0]  forState:UIControlStateNormal];
[btnTest addTarget:self action:@selector(clearDateEdit:) forControlEvents:UIControlEventTouchUpInside];
btnTest.frame = CGRectMake(0.0, 0.0, 50, 30);
[self.toolbar addSubview:btnTest];
[btnTestItem release];
