Does "bridge.callHandler()" makes submitForm() failure？

[bingbingBang]

My english is poor but I hope you can understand ：）

There is a web page in my app and I added some example javascript API by using 'WKUserScript' in WKWebView, this web page has a button like this :
"<button onclick="return submitForm()" name="save" class=...."

I add a event listener in connectWebViewJavascriptBridge() :

connectWebViewJavascriptBridge(function(bridge) {

 bridge.init(function(message, responseCallback) {
            responseCallback("Right back atcha")
           })

var elements = document.getElementsByName("save")
var saveBtn = elements[0]
saveBtn.addEventListener("click", function() {
                        bridge.callHandler('settingPageCallBack', {'foo': 'bar'})
                        }, false)
})

When I run my app use these javascript code the web page will get stuck when I click save button, but if I delete 'bridge.callHandler('settingPageCallBack', {'foo': 'bar'})' the save button will submit success, I don't know how to fix this, any advice?

I believe this may be fixed in v5.0.1.

When you switch to the new version, please note that the API has changed. In particular, make sure that you use the javascript setup code, as it has changed: https://github.com/marcuswestin/WebViewJavascriptBridge#usage

If you are still having trouble when using v5.0.x, feel free to reopen.

Cheers!
