Cannon make “render_row_cb” work

Hello. I’ve been trying to make “render_row_cb” work, because I want to input the row and the input html myself, I cannot make it work. When I copy the example code from the documentation, it does not render the row itself, it only renders the string “cmb_test_render_row_cb”, and that’s it. Here my code.

$cmb->add_field( array(
			'name' => 'Test render_row_cb (manaully rendered)',
			'desc' => 'field description (optional)',
			'id'   => 'wiki_testrender_row_cb',
			'type' => 'text',
			'render_row_cb' => 'cmb_test_render_row_cb',
		) );

public function cmb_test_render_row_cb( $field_args, $field ) {
		$id          = $field->args( 'id' );
		$label       = $field->args( 'name' );
		$name        = $field->args( '_name' );
		$value       = $field->escaped_value();
		$description = $field->args( 'description' );
		?>
		<div class="custom-field-row">
			<p><label for="<?php echo $id; ?>"><?php echo $label; ?></label></p>
			<p><input id="<?php echo $id; ?>" type="text" name="<?php echo $name; ?>" value="<?php echo $value; ?>"/></p>
			<p class="description"><?php echo $description; ?></p>
		</div>
		<?php
	}

Now I see it says “This is mainly to edit the markup that surrounds each individual field, not to edit the field itself.”. How to edit tie fields itself? I just have a select and I want to add data attributes on each OPTION, not on the select itself, on each option.
Ex: <option value="test" data-num="1">Teest</option>
