State handler within repeater problem item duplicate

Hi there,

I have built a custom SiteOrigin widget which has one repeater inside. That repeater has State emitter field and a few State handler fields inside.
The problem arises when I duplicate repeater’s item. State handler fields are not working anymore in that second (duplicated) repeater’s item. When i save/update the page, everything works normal again.

Could anyone help me with this?

here is my repeater code:

'test_collapse_repeater' => array(
    'type' => 'repeater',
    'label' => __( 'Collapse' , 'test-widgets-bundle' ),
    'item_name'  => __( 'Collapse Item', 'test-widgets-bundle' ),
    'item_label' => array(
        'selector'     => "[id*='test_collapse_title']",
        'update_event' => 'change',
        'value_method' => 'val'
    ),
    'fields' => array(
        'test_collapse_name' => array(
            'type' => 'text',
            'label' => __( 'Name', 'test-widgets-bundle' ),
            'optional' => false,
        ),

        'test_collapse_choose_media_type'  => array(
            'type'    => 'radio',
            'label'   => __( 'Choose Media type?', 'test-widgets-bundle'  ),
            'default' => 'image',
            'options' => array(
                'image'     => __( 'Image', 'test-widgets-bundle' ),
                'icon'      => __( 'Icon', 'test-widgets-bundle' ),
                'initials'  => __( 'Initials', 'test-widgets-bundle' ),
            ),
            'state_emitter' => array( 
                'callback' => 'select',
                'args' => array(
                        'test_collapse_choose_media_type_{$repeater}'
                    )
             ),
        ),
        'test_collapse_image' => array(
            'type' => 'media',
            'label' => __( 'Image', 'test-widgets-bundle' ),
            'choose' => __( 'Choose image', 'test-widgets-bundle' ),
            'update' => __( 'Set image', 'test-widgets-bundle' ),
            'library' => 'image',
            'state_handler' => array(
                'test_collapse_choose_media_type_{$repeater}[image]'    => array('show'),
                'test_collapse_choose_media_type_{$repeater}[icon]'     => array('hide'),
                'test_collapse_choose_media_type_{$repeater}[initials]' => array('hide'),
            )
        ),
        'test_collapse_icon' => array(
                'type'  => 'icon',
                'label' => __( 'Choose Icon', 'test-widgets-bundle' ),
                'state_handler' => array(
                    'test_collapse_choose_media_type_{$repeater}[image]'    => array('hide'),
                    'test_collapse_choose_media_type_{$repeater}[icon]'     => array('show'),
                    'test_collapse_choose_media_type_{$repeater}[initials]' => array('hide'),
                )
        ),
        'test_collapse_initials' => array(
            'type' => 'text',
            'label' => __( 'Initials', 'test-widgets-bundle' ),
            'state_handler' => array(
                'test_collapse_choose_media_type_{$repeater}[image]'    => array('hide'),
                'test_collapse_choose_media_type_{$repeater}[icon]'     => array('hide'),
                'test_collapse_choose_media_type_{$repeater}[initials]' => array('show'),
            )
        ),
    )
)

Thanks!
