"aocolumndefs": [               { "atargets": [ 2 ], "bsortable": false },               { "atargets": [ 2 ], "bsearchable": false },               { "atargets": [ 2 ],               "mrender": function ( data, type, full ) {               var url_ = full[1];               return '<div style="text-align: center;">'+               '<a href="javascript:void(0)" title="t&eacute;l&eacute;charger" onclick="telecharge("'+url_+'")">'+               '<button class="btn btn-mini"><i class="icon-download-alt"></i></button>'+               '</a>'+               '</div>';               } }                        ]

you need nest quotes , need escape inner quotes.

'<a onclick="telecharge(\''+url_+'\')">'
