Typescript Nativescript-添加新值时，数据不会刷新/更新

我的应用程序在添加新值时不刷新/更新标签或其他输入，这是一个非常奇怪的问题，因为添加值的函数工作正常，但视图没有使用新值刷新，我只有在单击“上一步”按钮时才能看到新值。你可以在这个视频中看到这个bug。

TNS版本是3.3.1

我的代码： view.html

<ActionBar class="action-bar" >
        <Label class="action-bar-title title" [text]="hostname"></Label>
        <NavigationButton text="{{ 'msg_btn_close' | translate }}" icon="res://ic_chevron_left_white_24dp" (tap)="goBack()"></NavigationButton>
</ActionBar>
<TabView #proxyTabView>
        <StackLayout *tabItem="{iconSource: 'res://ic_dashboard_black_24dp'}">
                <GridLayout columns="*,*,*,*" rows="auto, 180, 180">
                        <GridLayout colSpan="4" columns="*" row="0">
                                <RadDataForm tkExampleTitle tkToggleNavButton #proxyServerForm [source]="proxyData">
                                        <TKEntityProperty tkDataFormProperty name="hostname" displayName="{{ 'msg_ip_hostname' | translate }}" index="1">
                                                <TKPropertyEditor tkEntityPropertyEditor>
                                                        <TKPropertyEditorStyle tkPropertyEditorStyle labelHidden="false" labelTextSize="15"ios:labelFontName="Questrial" android:labelFontName="Questrial-Regular" labelPosition="Top"></TKPropertyEditorStyle>
                                                </TKPropertyEditor>
                                                <TKNonEmptyValidator tkEntityPropertyValidators errorMessage="{{ 'msg_error_ip_empty' | translate }}" ></TKNonEmptyValidator>
                                        </TKEntityProperty>
                                </RadDataForm>
                        </GridLayout>
                </GridLayout>
        </StackLayout>
        <StackLayout *tabItem="{iconSource: 'res://ic_http_black_24dp'}">
                <Label text="This is Label in Tab 2"></Label>
        </StackLayout>
        <StackLayout *tabItem="{iconSource: 'res://ic_memory_black_24dp'}">
                <Label text="This is Label in Tab 2"></Label>
        </StackLayout> 
        <StackLayout *tabItem="{iconSource: 'res://ic_network_check_black_24dp'}">
                <Label text="This is Label in Tab 2"></Label>

在ngOnInit上使用NgZone inside修复问题

ngOnInit() {
        this.hostname ="Loading data"
        this.worker.onmessage = (msg) =>{
                        this.zone.run(() => {
            if (msg.data!=="error"){
                this._proxyData = new ProxyData(msg.data.os.hostname);
                this.hostname=msg.data.os.hostname
                console.log(msg.data.os.hostname);
            }
                        });
        }
        this.worker.onerror = (e) =>{
            console.log(e.message);
        }
    }

ngOnInit() {
        this.hostname ="Loading data"
        this.worker.onmessage = (msg) =>{
                        this.zone.run(() => {
            if (msg.data!=="error"){
                this._proxyData = new ProxyData(msg.data.os.hostname);
                this.hostname=msg.data.os.hostname
                console.log(msg.data.os.hostname);
            }
                        });
        }
        this.worker.onerror = (e) =>{
            console.log(e.message);
        }
    }
