Error in loading daemon plist

Question

I'm trying to a Load LaunchDaemon plist from my Mac Application.When i try to load it in terminal it loads successfully, but when i try to load it thru my code, it doesn't work.
          Here is my code :
          OSStatus status;
          AuthorizationRef authorizationRef;
    status = AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &authorizationRef);
    if (status != errAuthorizationSuccess)
        NSString *err = [NSString stringWithFormat:@"Error Creating Initial Authorization : %d", status];
        [self ShowErrorAndExit:err];
    // kAuthorizationRightExecute == "system.privilege.admin"
    AuthorizationItem right = {kAuthorizationRightExecute, 0, NULL, 0};
    AuthorizationRights rights = {1, &right};
    AuthorizationFlags flags = kAuthorizationFlagDefaults |
    kAuthorizationFlagInteractionAllowed |
    kAuthorizationFlagPreAuthorize |
    kAuthorizationFlagExtendRights;
    // Call AuthorizationCopyRights to determine or extend the allowable rights.
    status = AuthorizationCopyRights(authorizationRef, &rights, NULL, flags, NULL);
    if (status != errAuthorizationSuccess)
        NSString *err = [NSString stringWithFormat:@"Sorry, we need Administrator priviliges to Continue"];
        [self ShowErrorAndExit:err];
          // After getting the Authorization Reference, executing the launchctl to load my LaunchDaemon
          char *daemonplist="/Library/LaunchDaemons/com.myappdaemon.plist";
          char *launchctl="/bin/launchctl";
          char *launchdArgs[]={"load",daemonplist,NULL};
          FILE *ldpipe=NULL;
          OSStatus;
          status=AuthorizationExecuteWithPrivileges(authorizationRef,launchctl,kAuthorizationFlagDefaults,launchdArgs,&ldpipe);
          if(status!=errAuthorizationSuccess)
          NSLog(@"Error:%d",status);
          if(status==errAuthorizationSuccess)
                    NSLog(@" succesfully loaded the daemon plist);
          status=AuthorizationFree(authorizationRef,kAuthorizationFlagDestroyRights);
          My plist :
          <key> Label</key>
          <string>com.myappdaemon</string>
          <key>Program</key>
          <string>/Applications/myapplication.app/Contents/MacOS/myappdaemon</string>
          <key>ProgramArguments</key>
          <array>
          <string>/Applications/myapplication.app/Content/MacOs/myappdaemon</string>
          </array>
          <key>WorkingDirectory</key>
          <string>/Library/myapplication</string>
          <key>StandardOutPath</key>
          <string>/dev/null</string>
          <key>StandardErrorPath</key>
          <string>/dev/null</string>
          <key>RunAtLoad</key>
          </true>
          <key>keepAlive</key>
          <true/>
          Thing is it shows the daemon plist is loaded successfully, but it's not. And After system restart the daemon starts fine. The plist loads fine in terminal. I have even tried with '-w' & '-F' to force load the daemon, but it doesn't loads at all. The weird thing is it just keeps saying that the daemon is loaded.
          Now what am i doing wrong here ..?
