How to refresh the entire page without hard reload

I have a Section with a detail. If a field of a particular record in the detail is modified , the record name should be added as a field value in the section. 

I have written a refresh script task and have the update script. But it seems to be not working. On hard reload the update happens.

This is my scrip task code: 

UserConnection userConnection = Get("UserConnection");

Guid jobflowId = Get("JobFlowID");

string senderName = "UpdateSelectedCandidate";

string message = JsonConvert.SerializeObject(new {

    RecordId = jobflowId

});

MsgChannelUtilities.PostMessage(userConnection, senderName, message);

return true;

This is my edit page code for refresh :

onEntityInitialized: function() {

                // onEntityInitialized method parent realization is called.

                this.callParent(arguments);

this.Terrasoft.ServerChannel.on(Terrasoft.EventName.ON_MESSAGE, this.onMessageReceived, this);

            },

                destroy: function() {

                this.Terrasoft.ServerChannel.un(Terrasoft.EventName.ON_MESSAGE, this.onMessageReceived, this);

                this.callParent(arguments);

            },

            onMessageReceived: function(sender, message) {

                if (message && message.Header && message.Body) {

                    var result = this.Ext.decode(message.Body);

                    //window.alert(message.Header.Sender);

                    //window.alert(message.Body);

                    if (message.Header.Sender === "UpdateSelectedCandidate" && this.get("Id") === result.RecordId) {

                        this.updateSectionCard({sectioncard: "UsrJobFlow1Page"});

                    }

                }

            }

I am aware that if a detail has to be refreshed the method name is this.updateDetail({detail: "Name of the detail"}). 

But if the entire edit page has to be refreshed i do not know the method name. 

Kindly help me resolve the same asap

Thanks & Regards,
