Thanks Nuno for saving my day. I was able to get the minor version data using 'v0' through coreservice from which am passing it to the js file. Please find below the code snippet.

Client client = new Client(); string tcmid = "tcm:222-7316-64"; IdentifiableObjectData identifiableObjectData = client.Read(tcmid, null); if (identifiableObjectData == null) return; FullVersionInfo fullVersionInfo = identifiableObjectData.VersionInfo as FullVersionInfo; if (!fullVersionInfo.LockType.Value.HasFlag(LockType.NewItem)) { client.Impersonate("NT AUTHORITY\\SYSTEM"); identifiableObjectData = client.Read(tcmid + "-v0", null); }
