OnClicked property sends data back to Go, but slot isn't invoked - qt

Question

So, I am trying to write a simple login page in Qml, the user writes data in the two text fields, and once the login button is pressed the Go Slot will send some data over to another function for authentication.
The only problem is, when the login button is pressed, the slot isn't invoked, the code continues outside the main loop that creates the UI and exits the program with a SIGSEV.
Basically going past:
// Execute app
gui.QGuiApplication_Exec()
and exiting MakeUI()
With this error:
fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x80 addr=0x0 pc=0x265a014]
Here's my Go Code:
package UI
import (
"fmt"
_ "github.com/heyuan110/gorepertory/logger"
"github.com/therecipe/qt/core"
"github.com/therecipe/qt/gui"
"github.com/therecipe/qt/qml"
"github.com/therecipe/qt/quickcontrols2"
"os"
)
type QmlBridge struct {
core.QObject
//_ func(username string,password string) bool `signal:sendToQml`
_ func(username string,password string )bool `slot:sendToGo`
}
func MakeUI() {
//var QmlBridgeVar *QmlBridge
var QmlBridgeVar = NewQmlBridge(nil)
// Create application
app := gui.NewQGuiApplication(len(os.Args), os.Args)
// Enable high DPI scaling
app.SetAttribute(core.Qt__AA_EnableHighDpiScaling, true)
// Use the material style for qml
quickcontrols2.QQuickStyle_SetStyle("material")
// Create a QML application engine
engine := qml.NewQQmlApplicationEngine(nil)
engine.RootContext().SetContextProperty("QmlBridgeVar", QmlBridgeVar)
//QmlBridgeVar.ConnectSendToQml(func(username string,password string){
//
//})
QmlBridgeVar.ConnectSendToGo(func(username string, password string){
fmt.Println(username,password)
})
// Load the main qml file
engine.Load(core.NewQUrl3("qml/main.qml", 0))
// Execute app
gui.QGuiApplication_Exec()
}
And here's my Corresponding Qml:
import QtQuick 2.0
import QtQuick.Controls 2.1
import QtQuick.Window 2.2
import QtQuick.Layouts 1.3
ApplicationWindow {
visible: true
title: "Bouncer"
property int margin: 11
minimumWidth: 600
minimumHeight: 450
ColumnLayout {
id: mainLayout
anchors.fill: parent
anchors.margins: margin
GroupBox {
id: rowBox
title: "Login"
Layout.fillWidth: true
RowLayout {
id: rowLayout
anchors.fill: parent
TextField {
id: usernameField
placeholderText: "Username"
Layout.fillWidth: true
}
TextField {
id: passwrdField
placeholderText: "Password"
Layout.fillWidth: true
}
Button {
id: loginButton
text: "Login"
MouseArea{
id: loginMouseArea
anchors.fill: parent
onClicked: QmlBridgeVar.sendToGo(usernameField.text, passwrdField.text)
}
}
}
}
}
}
I am prone to believe I might have some problems with the Qt bindings for go? Though I am not entirely sure. If anybody can give me valuable feedback I'd highly appreciate it.
