isaFormRepeater does not send select element name value via ajax request

[udemethegrtman]

Thanks for your plugin, but i have an issue with it

when i added this

<select id="parent_field_id[1][test_sub1]" name="parent_field_id[1][test_sub1]" class="form-control repeat-el" required>
	<option> {{ ( isset($parentInfo) ) ? $parentInfo->parent_title : 'Choose' }} </option>
	<option value="Mr">Mr</option>
	<option value="Mrs">Mrs</option>
	<option value="Dr">Dr</option>
	<option value="Ms">Ms</option>
	<option value="Master">Master</option>
</select>

<select id="parent_field_id[1][test_sub5]" name="parent_field_id[1][test_sub5]" class="form-control up_type repeat-el" required>
	<option> {{ ( isset($parentInfo) ) ? $parentInfo->relationship : 'Choose' }} </option>
	<option value="Mother">Mother</option>
	<option value="Father">Father</option>
	<option value="Uncle">Uncle</option>
	<option value="Aunty">Aunty</option>
	<option value="Nephew">Nephew</option>
	<option value="Brother">Brother</option>
	<option value="Sister">Sister</option>
	<option value="Guardian"> Guardian </option>
</select>

it repeated the parent elements, but when i send an ajax request, the first parent element displayed

parent_field_id[1][test_sub1]: Choose
parent_field_id[1][test_sub2]:
parent_field_id[1][test_sub3]:
parent_field_id[1][test_sub4]:
parent_field_id[1][test_sub5]: Choose
parent_field_id[1][test_sub6]:
parent_field_id[1][test_sub7]:
parent_field_id[1][test_sub8]:
parent_field_id[1][test_sub9]:
parent_field_id[1][test_sub10]:

but i when i click the add button the cloned form does not display the select element name value.

parent_field_id[2][test_sub2]:
parent_field_id[2][test_sub3]:
parent_field_id[2][test_sub4]:
parent_field_id[2][test_sub6]:
parent_field_id[2][test_sub7]:
parent_field_id[2][test_sub8]:
parent_field_id[2][test_sub9]:
parent_field_id[2][test_sub10]:

Where "[test_sub1]" and "[test_sub5]" are select elements.
