     - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier = @"Cell";
    CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if(cell == nil){
    [[NSBundle mainBundle] loadNibNamed:@"CustomCell_iPhone" owner:self options:nil];
        cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
        cell = categoryCustomCell;
    } 
     NSInteger pCat_id = [[[arrayCategoryData objectAtIndex:indexPath.row] 
    // call your method from here.. and put your method in this file then it will work for you
 [cell.btnAddCounter addTarget:self action:@selector(addCounter:pCat_id) forControlEvents:UIControlEventTouchUpInside];

    return cell;

}
