Angular directive link function called twice

Question

In my angular app, directives are working fine during the first visit, but once a page been visited twice, all the directive link function gets called twice too. Say I am on page A, click a link to go to page B and then back to page A, all directives on page A will execute the their link function twice. if I refresh the browser it will become normal again.

Here is an example where the console.log will output twice when the second visit.

  @app.directive 'testChart', ["SalesOrder", (SalesOrder) ->
    return {
      scope: {options: '='}
      link: (scope, elem, attrs) ->
        console.log("............checking")
        SalesOrder.chart_data (data) ->
          Morris.Line
            element: "dash-sales"
            data: data
            xkey: 'purchased_at'
            ykeys: ['total']
            labels: ['Series a']
    }
  ]

Any idea?

Update

My Route

when("/dash", { templateUrl: "<%= asset_path('app/views/pages/dash.html') %>", controller: DashCtrl }).

so my chart is duplicated

also make sure you are not including your directive in your index.html TWICE!
