Concatenate two JSON responses in wso2 esb - json

Question

I have two json from two different endpoints, i need to concatenate to convert it into a single valid json. I did it, but the first WSO2 json returns it as a string (firstjson). I would like it to be all a json.
FIRST JSON
{
"first": true,
"second": {
"name": "manoj",
"age": "45"
},
"third": {
"fourth": [
{
"class": "test12",
"salary": "123456"
},
{
"class": "test23",
"salary": "15678"
}
],
"fifth": "hello"
}
}
SECOND JSON
[
{
"item1": "123456",
"item2": "5678"
},
{
"item1": "8976",
"item2": "abcd"
}
]

Where am I wrong ?
Thanks in advance guys

Ok guys,
I solved it, I was wrong with the payloadFactory, the format it had to be of type json.
<payloadFactory media-type="json">
<format>
{
"completeJson" : {
"firstjson" : $1,
"secondjson" : $2
}}
</format>
<args>
<arg expression="get-property('first-json')" />
<arg expression="$body" />
</args>
</payloadFactory>
thanks anyway guys :)
