UITableView not reloading the Data

Question

Hello,
I am new to Xcode and i am facing problem with UITableview , What my app is doing is getting the list of the items from internet and show in (View 1) which have UITableView and working good (no problem in it) now after that as soon i click on any item it takes to (View 2) which shows Selected Item Details and i have Grouped Style UITableView (4 Sections and each have 3 rows and each rows have UITextField) in it. this step also work fine now as soon i go back to (View 1) and select any other item and when i see (View 2) the data in rows didn't changed below is the following code :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *MyCell = [NSString stringWithFormat: @"%d:%d", [ indexPath indexAtPosition: 0 ], [ indexPath indexAtPosition:1 ]];
cell = [tableView dequeueReusableCellWithIdentifier:MyCell];
if (cell == nil) {
UITableViewCell *cell = [[[UITableViewCell alloc ] initWithFrame: CGRectZero reuseIdentifier: MyCell] autorelease ];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
// Creating UITableField In Each Rows of Each Sections
[self CreateUIFieldWithData:indexPath :cell];
return cell;
now after i have facing the problem what i did is below :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *MyCell = [NSString stringWithFormat: @"%d:%d", [ indexPath indexAtPosition: 0 ], [ indexPath indexAtPosition:1 ]];
UITableViewCell *cell = [[[UITableViewCell alloc ] initWithFrame: CGRectZero reuseIdentifier: MyCell] autorelease ];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
// Creating UITableField In Each Rows of Each Sections
[self CreateUIFieldWithData:indexPath :cell];
return cell;
after doing this everything is working fine and data is reloading also but but this is creating a new problem is that if i open the view 2 for adding the new item and as soon i enter the something in UITextField and scroll down and scroll up everything which i type is gone. i know why its doing that but i m stuck now and i don't know what to do.

I m using Multi-View Based Template
so can you tell me how to delete the data from reuse queue??
also let me show the code which is adding the UIFieldText and data on it.
below is the code for View 2
- (void) CreateUIFieldWithData:(NSIndexPath *)myPath:(UITableViewCell *)myCell{
if (myPath.section == 0) {
if (myPath.row == 0){
UITextField *myField1 = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 280, 25)];
myField1.placeholder = @"App Name";
myField1.tag = 101;
if (isEdit == TRUE){
myField1.text = [CopyArrInfo objectAtIndex:2];
NSLog(@"Field 1 : %@" , [CopyArrInfo objectAtIndex:2]);
[myField1 addTarget:self action:@selector(DoneKeyBoard:) forControlEvents:UIControlEventEditingDidEndOnExit];
if (myCell != nil) {
[myCell.contentView addSubview:myField1];
[myField1 release];
AppName = (UITextField *)[myCell viewWithTag:101];
// Section 0 Row 2
if (myPath.row == 1){
UITextField *myField2 = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 280, 25)];
myField2.placeholder = @"App Target Audience";
myField2.tag = 102;
if (isEdit == TRUE){
myField2.text = [CopyArrInfo objectAtIndex:4]; // App Target Audience
[myField2 addTarget:self action:@selector(DoneKeyBoard:) forControlEvents:UIControlEventEditingDidEndOnExit];
if (myCell != nil) {
[myCell.contentView addSubview:myField2];
[myField2 release];
