How does one set the label on a (programmatically created) custom field?

Hello,

I've set up my custom input using the following action/filter hooks:
add_filter('gform_add_field_buttons',
array(
'someClass',
'gravityCreateAdminElement'
));

// Title the button
add_filter('gform_field_type_title',
array(
'someClass',
'gravitySetAdminElementTitle'
));
add_action("gform_field_input",
array(
'someClass',
'gravityCreateInputElement'
), 10, 5);

What does one need to do in order to set the label correctly for these two points?
1. Entry details (currently displays, "untitled").
2. Form edit window (currently displays, "untitled")

Thanks!
