Hi Shankar:

Since the One2many field is rendered by a template named 'web.X2ManyField', which includes ListRenderer and KanbanRenderer as its components. Check the file in: addons/web/static/src/views/fields/x2many/x2many_field.xml.

So, there are 2 ways you can seperate the list views between regular list and  o2m list:

1、overwrite the web.ListRenderer in "primary" mode, leaving the original template as it is.

​​In xml file:

        <t t-name="your_module.ListRenderer" t-inherit="web.ListRenderer" t-inherit-mode="primary" owl="1">
        <xpath ...>
            ...
         </xpath>
     </t>

​and then in .js file, you need to replace the ListRenderer's template with the above one:

	​	​ListRenderer.template = "your_module.ListRenderer";

2、Inherit the web.ListRenderer as you did,  and overwrite the 'web.X2ManyField' including a template reverting the ListRenderer as its component.  

I think this way is more complex and redundant, personally i prefer to the above one.
