Customize the tooltip of Chart.js - vuejs2

Question

I'm using the last version of vue and vue-chart.js.
I'd like to customize the tooltip which is displayed when hovering a point.
Issue
The tooltip is not changed from the default one
Question
How to customize the tooltip. Ultimately I'd like to be able to click on a link in the tool tip to trigger a dialog that would display details taken from data contained in my vue component.
Vue.component('line-chart', {
extends: VueChartJs.Line,
mounted () {
this.renderChart({
labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
datasets: [
{
label: 'Data One',
backgroundColor: '#f87979',
data: [40, 39, 10, 40, 39, 80, 40]
}
]
}, {
tooltips: {
custom: function(tooltipModel) {
// Tooltip Element
var tooltipEl = document.getElementById('chartjs-tooltip');
// Create element on first render
if (!tooltipEl) {
tooltipEl = document.createElement('div');
tooltipEl.id = 'chartjs-tooltip';
tooltipEl.innerHTML = "<table></table>"
document.body.appendChild(tooltipEl);
}
// Hide if no tooltip
if (tooltipModel.opacity === 0) {
tooltipEl.style.opacity = 0;
return;
}
// Set caret Position
tooltipEl.classList.remove('above', 'below', 'no-transform');
if (tooltipModel.yAlign) {
tooltipEl.classList.add(tooltipModel.yAlign);
} else {
tooltipEl.classList.add('no-transform');
}
function getBody(bodyItem) {
return bodyItem.lines;
}
// Set Text
if (tooltipModel.body) {
var titleLines = tooltipModel.title || [];
var bodyLines = tooltipModel.body.map(getBody);
var innerHtml = '<thead>';
titleLines.forEach(function(title) {
innerHtml += '<tr><th>' + title + '</th></tr>';
});
innerHtml += '</thead><tbody>';
bodyLines.forEach(function(body, i) {
var colors = tooltipModel.labelColors[i];
var style = 'background:' + colors.backgroundColor;
style += '; border-color:' + colors.borderColor;
style += '; border-width: 2px';
var span = '<span class="chartjs-tooltip-key" style="' + style + '"></span>';
innerHtml += '<tr><td>' + span + body + '</td></tr>';
});
innerHtml += '</tbody>';
var tableRoot = tooltipEl.querySelector('table');
tableRoot.innerHTML = innerHtml;
}
// `this` will be the overall tooltip
var position = this._chart.canvas.getBoundingClientRect();
// Display, position, and set styles for font
tooltipEl.style.opacity = 1;
tooltipEl.style.left = position.left + tooltipModel.caretX + 'px';
tooltipEl.style.top = position.top + tooltipModel.caretY + 'px';
tooltipEl.style.fontFamily = tooltipModel._fontFamily;
tooltipEl.style.fontSize = tooltipModel.fontSize;
tooltipEl.style.fontStyle = tooltipModel._fontStyle;
tooltipEl.style.padding = tooltipModel.yPadding + 'px ' + tooltipModel.xPadding + 'px';
}
},
responsive: true,
maintainAspectRatio: false
})
}
})
var vm = new Vue({
el: '.app',
data: {
message: 'Hello World'
}
})
