Option OnClick event

[g-trema]

Hi!
Thank you for this laravel package!

I have a chart built with an onClick option like this one:

onClick:function(c,i){
  e = i[0];
  var id = this.data.labels[e._index];
  var page = "index.php?product=" +id;
  document.location.href=page;
}

How can I pass this option through the controller ?
I tried some things, but nothing works.

Thank you for your help!

Edit:
Same question with the tooltips option:

tooltips: {
   callbacks: {
       label: function(item, data) {
              var label = data.datasets[item.datasetIndex].label;
              var value = data.datasets[item.datasetIndex].data[item.index];
              if (value === 0.08) {
                     value = 0;
              }

               return label + ': ' + value;
              }
       }
}

... it was a stupid question...
Solution: I use the optionsRaw function.

$options = "{onClick:function(c,i){
                    	  var e = i[0];
                    	  var id= this.data.labels[e._index];
                    	  alert(montre);
 }}";

and in my variable $chartjs :
->optionsRaw($options)
