ExtJS Classic 7.3.0: Renderer for checkbox column in grid is not showing a checkbox

If I don't use renderer, checkbox is shown. If I use renderer, true/false value is shown. I need to do some processing in the renderer before setting the value to true/false, hence I need to use renderer.

Here is a fiddle explaining my issue: Fiddle

Edit: I have a model A that has an association of hasOne model B. And both these models load from a different store. The grid store has to be of model A, because that’s the main store. And the checkbox field is in model B. So to show the checkbox value, I use a renderer where I get the model B, and then need to set the checkbox value

What are you trying to do doesn't make too much sense. The point of renderer is to alter what will you put into the cell. As you used checkcolumn you asked the column to put a checkbox into to column instead of text/record value. If you add a renderer function to a checkcolumn you simply voids the checkcolumn's default behaviour. If you really want this, simply add this to the end of your renderer function to see if fits your needs:

 return this.defaultRenderer(value);

But I really do think you are doing some anti-pattern there, and I would advise to rethink it, or try to explain it with a bit more detail.
