MobileFirst 6.3 invoking backend service created adapter procedure - soap

Question

I am having a hard time working out how to invoke my adapter which MobileFirst has created for me using the Discover Back End Service feature.
I created my adapter, and I am not using the following code to try and call it:
function callService(){
alert("Calling into Backend");
var options = {
onSuccess : loadSuccess,
onFailure : loadFailure,
invocationContext: {}
};
var params = {"itemRequiredReference":10};
var invocationData = {
adapter : 'SoapAdapter1',
procedure : 'inquireSingleService_inquireSingle',
parameters : [params]
};
WL.Client.invokeProcedure(invocationData, options);
}
But this does not seem to work. I get the error :
{"status":200,"invocationContext":{},"invocationResult":{"statusCode":500,"errors":[],"isSuccessful":true,"Envelope":{"SOAP-ENV":"http://schemas.xmlsoap.org/soap/envelope/","Body":{"Fault":{"":"","detail":{"CICSFault":{"CDATA":"DFHPI1010 02/02/2015 22:11:37 GENAPPA1 CPIH 00518 XML generation failed.

The generated adapter code looks like this :
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Generated code - Do not edit //
// //
// This is a SOAP adapter that was auto-generated by Worklight for invocation of specific SOAP-based services. //
// The adapter may invoke more than one service as long as they are all from the same enpdpoint (server host). //
// Each adapter procedure matches a single operation for the same endpoint server and accepts: //
// params - Serialized JSON representation of the XML-based SOAP body to be sent to the service //
// headers - Custom HTTP headers to be specified when invoking the remote service. It is a JSON object with //
// the headers names and values. E.g. { 'name1' : 'value1', 'name2' : 'value2' } //
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////
function inquireSingleService_inquireSingle(params, headers){
var soapEnvNS = '';
// The value of 'soapEnvNS' was set based on the version of the SOAP to be used (i.e. 1.1 or 1.2).
soapEnvNS = 'http://schemas.xmlsoap.org/soap/envelope/';
// The following mappings object was autogenerated from the XML schema of the input message to the service.
// It is being used to support a params JSON when invoking this procedure that don't specify the namespace
// prefix nor specifying whether a property is attribute or not.
//
// The 'roots' object has the list of message parts within the invocation SOAP message. Each entry has a
// mapping between the root element name and its namespace prefix and type.
// Each root object may define 'nsPrefix' and 'type'. Both are optional - If there is no need for a NS prefix
// then the 'nsPrefix' should not be specified. If the element is a simple type then the 'type' should not be
// specified.
//
// The 'types' object has a list of types each defining the children of the type and the definition of each
// child. If the child is a complext type, the 'type' property has a reference to the child type definition.
// Each child object may define:
// 'nsPrefix' (optional) - Holds the namespace prefix to be attached to the element. If there is no need for
// a NS prefix then the 'nsPrefix' should not be specified.
// 'type' (optional) - If the element is a simple type then the 'type' should not be specified. If it is an
// attribute then 'type' should have the value of '#'. Otherwise the value of 'type' is a reference to the
// type definition within the 'types' object.

I am a little lost - the parameters parameter on the invocationData object is what needs to be fixed - but its really very unclear what mapping as a json object I am meant to be passing as a parameter. Can somebody please show me what parameter I need to pass to set itemRequiredReference to the number 30.
If you need the WSDL I used to generate the service this is what I used : http://we.tl/fHgRos3f4e
This is the service being invoked from soapUI #idan :

Well I finally found a useful documentation page here :http://www-01.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.dev.doc/dev/c_invocation_generated_soap_adapter.html
and the solution was to set parameters variable to :
var params = {"inquireSingleRequest": {"itemRequiredReference": "10"}}
var invocationData = {
adapter : 'SoapAdapter1',
procedure : 'inquireSingleService_inquireSingle',
parameters : [params]
};
This allowed it to work perfectly.
