Xcode: 3.1.2

I have a NSTableView I am updating from a NSDictionary. The tableview has a checkbox that was added with IB. I can set the checkbox from the NSDictionary but I can't change it's status once it loads. I would like to allow for the status change and then when it does change run an action based of the key of the NSDictionary.

I am very new to Obj-c and am trying to work my way through this. I can track changes with - (void)tableView:(NSTableView *)tableView setObjectValue:(id)aData. what I can't figure out is how to capture the change update the NSDictionary and reload.

Thanks for any help.
- (id)tableView:(NSTableView *)tableView
objectValueForTableColumn:(NSTableColumn *)tableColumn
	NSArray *keysArray = [speakerDict allKeys];
	NSArray *sortedKeysArray =
	id keyAtRow = [sortedKeysArray objectAtIndex:row];
	if ([[tableColumn identifier] isEqualToString:@"speakerNameCell"])
		return keyAtRow;    
	return [speakerDict objectForKey:keyAtRow];
- (void)tableView:(NSTableView *)tableView setObjectValue:(id)aData 
   forTableColumn:(NSTableColumn *)aCol 
//???????	found this code elsewhere
id loc_id, loc_data;
	// identify the table column
	loc_id = [aCol identifier];
//the class comes up ica for my checkbox so this part isn't run
	if ([loc_id isKindOfClass:[NSString class]])
		// determine the old cell value
		loc_data = [[self speakerDict] objectForKey:loc_id];
		loc_data = [loc_data objectAtIndex:row];
		// compare the old cell value against the "new" value
		if (![loc_data isEqual:aData])
			// update the data buffer
//the designation for this dictionary is wrong getting warning that foo might not respond to speakerDict
			[[[self speakerDict] objectForKey:loc_id]
			 replaceObjectAtIndex:row withObject:aData];
