Unable to search innerText using: aqObject.CheckProperty(body, "innerText", cmpContains, str, false)

I'm trying to search a string using   aqObject.CheckProperty(body, "innerText", cmpContains, str, false)  where str = "test".

Script is unable to locate the string in this dropdown with checkbox. 

On a side note, script can search for other texts on the page in the internet explorer. Thank you
