How can I refresh a grid data source using angular Kendo UI

Question

I am combining Telerik Kendo grid with Angular using the Angular Kendo UI project.

I have the following markup:

<div kendo-grid="" k-options="thingsOptions" style="height: 600px;" />

and the following code in my controller:

    $scope.thingsOptions = {
        dataSource: {
            type: "json",
            transport: {
                read: "/OM/om/getAssets",
                dataType: "json"
            },
            schema: {
                model: {
                    id: "ProductID",
...

This all works fine however I would like to force a data source refresh of my grid from my controller. something like

 $scope.getTasks = function() {
    $scope.thingsOptions.dataSource.read();
};

Is this possible to do from the controller? I could always do something like

$("#taskGrid").data("kendoGrid").dataSource.read();

In my controller. But it seems a bit wrong to have to select a HTML element from my controller.

Just pass in a scope variable to the directive, then inside of your controller you can use the variable to call whatever widget methods you need.

<div kendo-grid="grid" ...></div>

<script>
  ...

  $scope.getTasks = function() {
    // scope.grid is the widget reference
    $scope.grid.refresh();
  }

  ...
</script>
