Expected behavior:

Steps to reproduce: I would like call to function of my controler when the user click on a button, but Chrome show an error error becuase doesn't find the function deleteReposition().

confirmDeleteReposition(){
    var a = $.confirm({
        lazyOpen: true,
        columnClass: 'medium',
        draggable: true,
        type: 'red',
        title: 'Confirmación',
        closeIcon: true,
        icon: 'glyphicon glyphicon-ok',
        content: '¿Deseas borrar el Registro de Reposición?',
        buttons: {

            si: function(){
               // I need call to this function to delete information in data base in Oracle
                this.deleteReposition();

            },
            no: function(){
