display a c++ created object in a qt quick application

Now I have a Qt Quick Application, version 2.4, and I want to use C++ code to create an object to display some text in the Qt application.

I've tried reading countless Qt documentation, from the source themselves, most of which examples don't even compile on their own.

So I wanted help on display a C++ function returned value in the Qt Quick Application. All my code will be attached below, hope this isn't too much to ask and thanks for answering in advanced.

//MainForm.ui.qml, the area I want to display the text.
import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Layouts 1.1

Rectangle {
    id: mainWindow
    color: "#302a2a"
    anchors.fill: parent

    Rectangle {
        id: equationAreaBackground
        height: parent.height - 400
        color: "#3f3737"
        anchors.right: parent.right
        anchors.rightMargin: 0
        anchors.left: parent.left
        anchors.leftMargin: 0
        anchors.top: parent.top
        anchors.topMargin: 0

        Text {
            id: equation
            color: "white"
            text: qsTr("The Equation comes here")
            anchors.fill: parent
            font.pixelSize: 64
        }
    }

    GroupBox {
        id: mainTable
        width: parent.width * 0.7
        height: parent.height * 0.4
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.top: equationAreaBackground.bottom
        anchors.topMargin: 0

        /* Period One (1) */
        Button {
            id: elementH
            x: 0
            y: 0
            width: parent.width/19
            height: parent.height/7
            text: qsTr("H")
        }

And I want to display some C++ struct data on click of Button with ID: elementH. It is found in another file element.cpp, with header file: element.h.

File: Element Header

#ifndef ELEMENT
#define ELEMENT

struct element{};

#endif // ELEMENT

File: Element Source

#include <string>
#include "element.h"

struct element
{
    // General Properties
    string name;
    string symbol;
    int atomicNumber;
    double atomicMass;
    string category;
    int group;
    char block;
    int period;
    string electronConfig;
    int valenceCount;

    // Physical Properties
    string color;
    string phase;
    double meltingPoint;
    double boilingPoint;
    // Others not yet necessary.
} elements[114];

void elementH()
{
    // General Properties
    elements[0].name = "Hydrogen";
    elements[0].symbol = "H";
    elements[0].atomicNumber = 1;
    elements[0].atomicMass = 1.0079;
    elements[0].category = "nonmetal";
    elements[0].group = 1;
    elements[0].block = "s";
    elements[0].period = 1;
    elements[0].electronConfig = "1";
    elements[0].valenceCount = 1;

    // Physical Properties
    elements[0].color = "colorless";
    elements[0].phase = "gas";
    elements[0].meltingPoint = 13.99;
    elements[0].boilingPoint = 20.271;
}

There is alot of other code involded, but it's mostly just repetition for other buttons. Thanks again.
