Response of JSON type

Hi Guys,

I'm using the below simple Get Webservice to return a JSON file, its working but the response is actually of Text type not JSON Type 

ClassMethod cmGetHomes(cnt1, cnt2) As %Status
{    S response="{""Land"""_":"_""""_cnt1_""",""Home"""_":"_""""_cnt2_"""}"
 // set dataObj=##class(%DynamicObject).%FromJSON(response.data)
 //set response.data = dataObj
 //W response.%ToJSON()
 //set response.data = {}.%FromJSON(response.data)
 //set response.data = {}.%FromJSON(response.data)
 W response
 Quit $$$OK
}

This is the response that I'm getting in Postman

But it says type is text not JSON 

Thanks
