Anyway to refresh the Quote screen when adding Product?

Hi everyone.

I'm trying to refresh the quote screen once a new product line is added. I can "force" this change by adding a checkbox and once that checkbox is ticked then it runs this.model.fetch(); which works fine.

However I want to automate this, I tried forcing the checkbox on the product save but it doesn't seem to work.

Is there anyway to refresh the Quote screen when a Product relationship is added?

Thanks,

Daniel
