FullCalendar Add Icon with myID - fullcalendar

Question

in the resources I would like to add an icon with an ID inside that I can pass on.
I tried with resourceLabelContent but it doesn't work for me
resourceGroupField: 'mygroup',
resourceColumns: [
{
labelText: 'Unità',
field: 'title',
},
{
labelText: 'Telefono',
field: 'Tel',
},
],
resources: {
url: 'fetch-resource.php',
method: 'POST',
},
resourceLabelContent: function (arg)
{
return { arg.resource.title + "'<i class="fas fa-users">'+arg.resource.myid+'</i>'"};
},

Answer 1

I solved it in part .... I modified the JS schduler so, in this way it puts the icons in the resources
ResourceRow.prototype.renderGutterHtml = function() {
var html, i, j, ref;
html = '';
for (i = j = 0, ref = this.depth; j < ref; i = j += 1) {
html += '<a href="#" class="far fa-envelope m-1 text-info sendMail"/></a>';
}
html += '<span class="fc-expander-space">' + '<a href="#" class="fas fa-chart-bar m-1 text-danger graphStat" color=red></a>' + '</span>';
return html;
};
then with "resourceRender" I go to assign the data-id, but then the click on the icon doesn't work
resourceRender: function(resource, cellEls) {
$('.graphStat').attr('data-id',resource.id);
$('.graphStat').on('click', function(e) {
alert($(this).data('id'));
});
},
what am I doing wrong
