React native Webview blocked after Screen Lock (IOS)

I'm working on an ios react native app, I'm using webview to get data periodically, and use it in my app, but when I lock my iphone device, the webview stop sending data to react native.

onWebViewLoad(){
   setInterval(function(){
      this.refs.webview.injectJavaScript('window.ReactNativeWebView.postMessage(window.getData());');
   },10000);
}

handleMessage(event){
   // receive data
   //doSomthing(event.nativeEvent.data)
}

// 
              ...
              <WebView
                source={{ uri: this.state.myPage}}
                javaScriptEnabled={true}
                startInLoadingState={true}
                onLoad={this.onWebViewLoad}
                ref="webview"
                onMessage={this.handleMessage}
                />
            ...

Note : code is working fine when app in foreground or background , but when I open the app and lock the screen the webview stops sending data.

is there a way to make the webview send data after screen lock.
