My NSMutable Array isn't adding a button - objective-c

Question

I'm trying to add button to a scroll view using a NSMutableArray. The code works fine in a twitter example I am using as a reference, but for some reason it is not working in this case. In the twitter search case the code is implemented in the main class. While in this case I am implementing it in the flipside view. Could anyone help me out since I am a bit new to Objective c.
Thanks in Advance.
Here is the init where the NSMutableArray Buttons is initialized
- (id)init
{
self = [super init]; // initialize the superclass members
if (self != nil) // if the superclass initialized properly
{
// creates list of valid directories for saving a file
NSArray *paths = NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory, NSUserDomainMask, YES);
// get the first directory
NSString *dir = [paths objectAtIndex:0];
// concatenate the file name "tagsIndex.plist" to the path
filePath = [[NSString alloc] initWithString:
[dir stringByAppendingPathComponent:#"tagsIndex.plist"]];
NSFileManager *fileManager = [NSFileManager defaultManager];
// if the file does not exist, create an empty NSMutableDictionary;
// otherwise, initialize an NSDictionary with the file's contents
if ([fileManager fileExistsAtPath:filePath] == NO)
{
tags = [[NSMutableDictionary alloc] init];
} // end if
else
{
tags = [[NSMutableDictionary alloc]
initWithContentsOfFile:filePath];
} // end else
buttons = [[NSMutableArray alloc] init]; // create array
infoButtons = [[NSMutableArray alloc] init]; // create array
}
return self; // if self == nil, object not initialized properly
} // end method init
Here we have the method where we are adding the object to the buttons array but it stays empty.
- (void)addNewButtonWithTitle:(NSString *)title
{
// create a new button
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
// give the button the title of the tag
[button setTitle:title forState:UIControlStateNormal];
// tell the button to call buttonTouched: when it is touched
[button addTarget:self action:#selector(buttonTouched:)
forControlEvents:UIControlEventTouchUpInside];
[buttons addObject:button]; // add the UIButton to the end of the array
//This Doesn't add it stays 0;
// sort the NSMutableArray by the UIButton's titles
[buttons sortUsingSelector:#selector(compareButtonTitles:)];
[self refreshList]; // refresh the list of favorite search Buttons
// Adjust the content size of the view to include the new button. The
// view scrolls only when the content size is greater than its frame.
CGSize contentSize = CGSizeMake(scrollView.frame.size.width,
buttons.count * (BUTTON_HEIGHT + BUTTON_SPACING) + BUTTON_SPACING);
[scrollView setContentSize:contentSize];
}
Here is the dealloc where I release the buttons array.
- (void)dealloc {
[buttons release];
[super dealloc];
}
I can't Figure out where the mistake is.
Here is the Code that is supposed to add a new button.
- (IBAction)addTag:sender
{
// make the keyboard disappear
[ItemTitleField resignFirstResponder];
[QuantityField resignFirstResponder];
NSString *key = ItemTitleField.text; // get the text in tagField
NSString *value = QuantityField.text; // get the text in queryField
// test if either field is empty
if (value.length == 0 || key.length == 0)
return; // exit from the method
if ([tags valueForKey:key] == nil) // test if the tag already exists
[self addNewButtonWithTitle:key]; // if not, add a new button
[tags setValue:value forKey:key]; // add a new entry in tags
ItemTitleField.text = nil; // clear tagField of text
QuantityField.text = nil; // clear queryField of text
[tags writeToFile:filePath atomically:NO]; //save the data
} // end method addTag:

- (void)addNewButtonWithTitle:(NSString *)title
{
// create a new button
// UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
UIButton *button = [[UIButton alloc] init];
or
UIButton *button = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
// give the button the title of the tag
[button setTitle:title forState:UIControlStateNormal];
// tell the button to call buttonTouched: when it is touched
[button addTarget:self action:#selector(buttonTouched:)
forControlEvents:UIControlEventTouchUpInside];
[buttons addObject:button]; // add the UIButton to the end of the array
//This Doesn't add it stays 0;
// sort the NSMutableArray by the UIButton's titles
[buttons sortUsingSelector:#selector(compareButtonTitles:)];
[self refreshList]; // refresh the list of favorite search Buttons
// Adjust the content size of the view to include the new button. The
// view scrolls only when the content size is greater than its frame.
CGSize contentSize = CGSizeMake(scrollView.frame.size.width,
buttons.count * (BUTTON_HEIGHT + BUTTON_SPACING) + BUTTON_SPACING);
[scrollView setContentSize:contentSize];
