Input field name is not populated on checkout page shipping address

I want to add a new field to my shipping address section on checkout page, I was able to achieve it by below code.

<item name="shippingAddress" xsi:type="array">     <item name="children" xsi:type="array">         <item name="shipping-address-fieldset" xsi:type="array">             <item name="children" xsi:type="array">                 <item name="location" xsi:type="array">                     <item name="component" xsi:type="string">Magento_Ui/js/form/element/abstract</item>                     <item name="label" xsi:type="string">Location</item>                     <item name="provider" xsi:type="string">checkoutProvider</item>                     <item name="visible" xsi:type="string">true</item>                     <item name="sortOrder" xsi:type="string">200</item>                     <item name="config" xsi:type="array">                         <item name="template" xsi:type="string">ui/form/field</item>                         <item name="elementTmpl" xsi:type="string">ui/form/element/input</item>                         <item name="tooltip" xsi:type="array">                             <item name="description" xsi:type="string" translate="true">Search your location.</item>                         </item>                     </item>                 </item>             </item>         </item>     </item> </item> 

The field is added to shipping address form but the name attribute is null. I need to set it as location but it always stays null. I have tried adding name and inputName attributes to xml but nothing seems to be working. Please check below as the html generated for my field.

<input class="input-text" type="text" data-bind="     value: value,     valueUpdate: 'keyup',     hasFocus: focused,     attr: {         name: inputName,         placeholder: placeholder,         'aria-describedby': getDescriptionId(),         'aria-required': required,         'aria-invalid': error() ? true : 'false',         id: uid,         disabled: disabled     }" name="" aria-invalid="false" id="YCYKNDR"> 

Do anyone have any idea how we can set name attribute for input field on shipping address section?
