    Dear all

    I have a jqxgrid with grouping and a groupsrenderer function. I need to be able to place a clickable ui element (e.g. a link or a button) inside the groups header. But how can I manage to bring the click event out to my scope – i.e. the scope, in which <jqx-grid> is placed? I tried different things:

    1) $emit
    Idea: Since the directive jqxgrid has its own scope, I should be able to fire an event to the parent scope (which is the scope containing the grid), catch the event an call my function.

    
    groupsrenderer: function (text, group, expanded) {
        return '<button ng-click="$emit(\'TEST\', \'test...\')">Activate</button>';
    }
    
    ...
    
    $scope.$on("TEST", function(event, message) {
        alert("hallo " + message);
    });
    

    However, this does not work. Why?

    2) using own directive

    
    groupsrenderer: function (text, group, expanded) {
        return '<my-directive></my-directive>';
    }
    

    According the example http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxangular/angularjs-datatable-custom-cell-template.htm, I tried to make my own directive and put it in the grouping header. But it seems, that this does not work; the directive template seems not to be evaluated / the DOM is not populated.

    Can somebody help me on this? – I really need a solution.
    Thanks in advance.

    Thank you, Dimitar.

    OK, this is the last possibility, if nothing else works. (But for sure not that nice…)
