Question

What is the best way to implement a unique function in an angularjs directive?

Is it possible to execute a custom function when clicking on the checkbox of a table row shown below? I am using the Angular Smart Table directive and need to be able to store the rowid or another property of the rows when the checkbox is clicked.

app.directive('csSelect', function () {
    return {
        require: '^stTable',
        template: '<input type="checkbox"/>',
        scope: {
            row: '=csSelect'
        },
        link: function (scope, element, attr, ctrl) {

            element.bind('change', function (evt) {
                scope.$apply(function () {
                    ctrl.select(scope.row, 'multiple');
                });
            });

            scope.$watch('row.isSelected', function (newValue, oldValue) {
                if (newValue === true) {
                    element.parent().addClass('st-selected');
                } else {
                    element.parent().removeClass('st-selected');
                }
            });
        }
    };
});

EDIT

This directive can be used as follows:

<td cs-select="row"></td>

If I add ng-click to the td element to check for a clicked row, clicking anywhere inside the td element will act as clicking on the row. This does not solve the issue regarding the checkbox behavior.

Include the ng-click directive in the template of the directive.

template: "<input type='checkbox' ng-click='myFunction()'/>"

Then, within the link or controller function of the directive:

scope.myFunction = function() { //Your code here };

To incorporate functions into your template HTML within your directive, simply include them in the scope parameter provided to your link function.

This method can be utilized for your change handler, and you can apply ngClass to determine whether a specific CSS class should be attached to your input element.

Consider implementing something similar to the following:

return {
  // ...,
  template: '<input ng-change="changeHandler()" ng-class="{'st-selected': row.isSelected}">',
  link: function (scope, elem, attrs, parentCtrl) {
    scope.changeHandler = function () {
      // parentCtrl.whatever(scope.row);
    };
  }
};

An essential addition that your input field lacks is an ngModel. While not fully comprehending the inner workings of your stTable directive, it is advisable to bind your checkbox directive to a model, such as row.isSelected.
