	Send a GET request:

	- (UITableViewCell )tableView:(UITableView )tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
	{
	UITableViewCell *cell =
	[tableView dequeueReusableCellWithIdentifier:REUSABLE_CELL_ID];

	UILabel label = (UILabel )[cell viewWithTag:VIEW_TAG];
	Model *someModel = [self getModelFromIndexPath:indexPath];

	// `takeUntil:` makes the RACObserve() signal complete (and thus breaks the subscription)
	// when the cell is recycled.
