How to apply Polyglot Detector function to dataframe

Assuming I have a column called df.Text which contains text (more that 1 sentence) and I want to use polyglot Detector to detect the language and store the value in a new column df['Text-Lang'] how do I ensure I also capture the other details like code and confidence

testEng ="This is English"
lang = Detector(testEng)
print(lang.language)

returns

name: English code: en confidence: 94.0 read bytes: 1920

but

df['Text-Lang','Text-LangConfidence']= df.Text.apply(Detector)

ends with

AttributeError: 'float' object has no attribute 'encode' and Detector is not able to detect the language reliably.

Am I applying the Detector function incorrectly or storing the output incorrectly or something else?
