Hello i got some trouble displaying some icons inside a column using __CSR__, what it should do is to check for the contents inside a document set and if the content is equal to a content type and add a corresponding icon. 

for this im returning a div with a custom class based on the id of the element so when i query the info i need it will update the content using this unique class.

But is not appending the content inside the div, the code inside the conditions seem to works, the query is getting the right data, but in the list the content is not being added.

Any help?? thanks!!

Example idea
