Custom UITableViewCell doesn't appear in the table

Question

Hi, I have created a UITableViewCell and I am trying to display it in one of my table, but for some reason it doesn't come, the table is coming empty. And when I click on the one of cell in the table it takes me down to next level, which means the custom UITableViewCell is not getting rendered properly.

Here is my custom UITableViewCell .h file

@interface ProductViewCell : UITableViewCell {
 IBOutlet UILabel *titleLabel;
 IBOutlet UILabel *detailLabel;
 IBOutlet UIImageView *imageView;
}

@property (nonatomic, retain) UILabel *titleLabel;
@property (nonatomic, retain) UILabel *detailLabel;
@property (nonatomic, retain) UIImageView *imageView;

Here is the .m file

#import "ProductViewCell.h"

@implementation ProductViewCell
@synthesize titleLabel, detailLabel, imageView;

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
   [super setSelected:selected animated:animated];
}
@end

Here is the .h file which subclasses UITableViewController

@interface ProductCategoryViewController : UITableViewController {
 NSArray *tableDataSource;

}

@property (nonatomic, retain) NSArray *tableDataSource;

Here is the .m file for ProductCategoryViewController

@implementation ProductCategoryViewController
@synthesize tableDataSource;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:   
            (NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    ProductViewCell *cell = (ProductViewCell*)[tableView   
                   dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
         cell = [[[ProductViewCell alloc] initWithStyle:UITableViewCellStyleDefault  
                  reuseIdentifier:CellIdentifier] autorelease];
    }

    NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row];

    cell.titleLabel.text = [dictionary objectForKey:@"name"];

    cell.imageView.image = [UIImage imageNamed:[dictionary objectForKey:@"imageUrl"]]; 
    return cell;
    }

Your help is appreciated.
