Swap out modal views dynamically

[rajeshsubramanian]

This works great and saved us a ton of time. Is there a way to replace the existing view inside the modal with another one dynamically? I have a backend process that takes a while to publish the content and would like to show a spinner gif in the modal while the content is being fetched. Once the content is available, I would like to swap out the spinner view with the actual content. I couldn't find a way to set the content at run time though.
