Ok anyway I solve it by myself. Here is the answer for other if have the same problem. Sorry if there’s bad practices in my js. I’m not a pro.

function pieChart2(){

    var chartContainer = $('.chart-container');

    chartContainer.each(function(index){
        var $this = $(this),
            canvas = $this.find('canvas'),
            ctx = canvas.get(0).getContext("2d"),
            chartData = [];

        $this.find('.chart-data').find('li').each(function(){
            var li = $(this);

            chartData.push({
                value: li.data('value'),
                color: li.data('color'),
                label: li.text()
            })
        });

        window.myDoughnut = new Chart(ctx).Doughnut(chartData, {
            segmentShowStroke : false,
            showTooltips: false,
            percentageInnerCutout : 55,
            legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"
        });
        var legend = myDoughnut.generateLegend();
        $this.append(legend);
    });

};
pieChart2();

To create new graphs to dynamics elements inserted you can create a DOM Observer. I create a fiddle with a example in 

	$(function () {
	  $('.graph').each(function(index, canvas) {
	    createGraph(
      	canvas, 
        $(canvas).data('labels'), 
        $(canvas).data('datasets'), 
        $(canvas).data('options')
      );
      $(canvas).data('renderizado', true);
	  });
    
    $(document).on('DOMNodeInserted', function(e) {
        if ($(e.target).hasClass('graph')) {
           createGraph(
             e.target, 
             $(e.target).data('labels'), 
             $(e.target).data('datasets'), 
             $(e.target).data('options')
           );
           $(e.target).data('renderizado', true);
        }
    });
    
    $('#adicionar').on('click', function () {
		  $('#graphs').append('<canvas width="400" height="250" class="graph" data-options=\'{"showLines": true}\' data-renderizado=false data-labels=\'["January","February","March","April","May","June","July"]\' data-datasets=\'[{"label":"My First dataset","fill":false,"lineTension":0.1,"backgroundColor":"rgba(75,192,192,0.4)","borderColor":"rgba(75,192,192,1)","borderCapStyle":"butt","borderDash":[],"borderDashOffset":0.0,"borderJoinStyle":"miter","pointBorderColor":"rgba(75,192,192,1)","pointBackgroundColor":"#fff","pointBorderWidth":1,"pointHoverRadius":5,"pointHoverBackgroundColor":"rgba(75,192,192,1)","pointHoverBorderColor":"rgba(220,220,220,1)","pointHoverBorderWidth":2,"pointRadius":5, "pointHitRadius":10,"data":[56, 55, 40, 65, 59, 80, 0]}]\'></canvas>');
			});
	});

	function createGraph (canvas, labels, datasets, options) {
		Chart.Line(canvas,{
	    data:{labels: labels, datasets: datasets},
	    options:options
	  });
	}
