UI5 Deep Insert is triggering the Create_Deep_Entity

Question

Dear All,
Here is my following code to post records to two tables.
var testObject = [ ];
  testObject.push(
         Mandt: "100",
         SignReqNo: "00100003",
         ServCode:"00100001",
         ImoNumber:"00900001",
         SignInDate:new Date("2014-10-01T00:00:00"),
         SignInRemarks:"Testin from UI5_2",
         SignStatus:"01"
  var child = [];
  child.push(
      Mandt:"100",
      SignReqINo:"00000001",
      SignReqNo:"00100003",
      CrewID:"00100002",
      ExpSignOut:new Date("2014-10-01T00:00:00")
  child.push(
      Mandt:"100",
      SignReqINo:"00000002",
      SignReqNo:"00100003",
      CrewID:"00100003",
      ExpSignOut:new Date("2014-10-01T00:00:00")
testObject[0].ZmaCrewSignItSet = child;
And attached is my data model.
Parent Entity Type -> ZmaCrewSign
Parent Entity Set -> ZmaCrewSignSet
Child Entity Type ->ZmaCrewSignIt
Child Entity Set -> ZmaCrewSignItSet
Parent Navigation Property -> ZmaCrewSignItSet
With this setup i am able to read the records in above mentioned structure.
But when i try to post records from UI5 using the above JS code, the method CREATE_DEEP_ENTITY is not getting triggered, instead the parent create_entity method its getting triggered while debugging.
PLEASE HELP ME TO RESOLVE THIS ISSUE.

Many Thanks Saurabh.
It was working after when i changed the type declaration in the create deep entity set method to get child values.
Incorrect:
  types:begin of ty_sign_set.
      include type ZMA_CREW_SIGN.
      types: ZmaSignReqIt TYPE ty_sign_req_it,
  end of ty_sign_set.
Correct One.
  types:begin of ty_sign_set.
      include type ZMA_CREW_SIGN.
      types: ZmaSignReqItSet TYPE ty_sign_req_it,
  end of ty_sign_set.
