Problem with creating node with multiple inport / outport

Hello,
I am creating a graph where each node can have multiple inport / outport. I am using same mechanism to create each type of node. But only outport is not creating for one type of node (Data) where other two type (Workflow, Service) is working fine.

var outport = 0;
var inport = 0;
var listOfInputPorts = [];
var listOfOutputPorts = [];

//create nodes using model data
self.nodes.forEach(function(node) {
	label = node.label;
	name = node.name;
	
	switch(label) {
  	  case "Workflow":
  		color = 'CadetBlue';
  	    break;
  	  case "Data":
  		color = 'SteelBlue';
  	    break;
  	case "Service":
  		color = 'Teal';
  		break;
  	default:
  		color = 'SteelBlue';
  	}
	
	self.linkDataArray.forEach(function(link) {
  		//output port definition
  			if(node.id == link.from){
  				outport++;
  				outport_lable = 'OUT ' + outport;
  				link.frompid = outport_lable;
  				var aNewOutputPort = makePort(outport_lable,false);
                listOfOutputPorts.push(aNewOutputPort);
  			}
  		});
	self.linkDataArray.forEach(function(link) {
  		//input port definition
  			if(node.id == link.to){
				inport++;
				inport_lable = 'IN ' + inport;
  					link.topid = inport_lable;
  					var aNewInputPort = makePort(inport_lable,true);
  	                listOfInputPorts.push(aNewInputPort);
  				}
      		});
  		
  		makeTemplate(label, color,
  				listOfInputPorts,
                listOfOutputPorts);
  		
  		listOfInputPorts = [];
        listOfOutputPorts = [];
  		outport = 0; 
  		inport = 0;
  });

Thanks for your time.
