Migx wrong data retreived using getImageList

I follow the instruction with this page http://rtfm.modx.com/extras/revo/migx/migx.tutorials/migx.simple-opening-hours-table#MIGX.Simpleopeninghourstable-ParsingtheData
i named the migx tv with "DisplayListTV"
when i going to use [[*DisplayListTV]] in template it return a json string with accurate data from the resource
however when i use [[getImageList?
&tvname=`DisplayListTV`
&tpl=`DisplayListRow`
]]
it doesnt return the right data
note: i have already DisplayListRow chunk

Thanks for any answers

if yes, then what?
