I've added a button to the Tree view, and in the action method I want to get active_ids

ListController.include({

    renderButtons: function () {
        this._super.apply(this, arguments);
        if (this.$buttons) {
            this.$buttons.find('.o_export_payslip').click(this.proxy('export_payslip'));
        }
    },

    export_payslip: function () {
        var self = this
        console.log(this)
        self.do_action({
            .......

        });
    }

});
