带controlEvent的UIbutton在UItableViewcell中不实现

Question

代码：

UIImageView *bgDetails = [[UIImageView alloc] initWithFrame: CGRectMake(0, 20, 320, 47)];
bgDetails.image = [UIImage imageNamed:@"bgDetail"];

UIButton *btnLike = [UIButton buttonWithType:UIButtonTypeCustom];
[btnLike setBackgroundImage:[UIImage imageNamed:@"38_38"] forState:UIControlStateNormal];
btnLike.frame = CGRectMake(278, 4.5f, 37, 37);
[btnLike addTarget:self action:@selector(doLike:) forControlEvents:UIControlEventTouchUpInside];

[bgDetails addSubview:btnLike];
[cell.contentView addSubview:bgDetails];

但是btnLike没有调用doLike方法,请帮忙，谢谢。
