Run function.php with confirm boostbox.js

I have a database.php file where I have the following functions:

class Conexao(){

    function Conexao(){}

    function Inserir(){}

    function Update(){}

    function select(){}

    function edit(){}

}

I have a pagina.php where I list the database data in PDO , in this página.php I have the edit , update , del and insert .

I have a script.js which when I click the edit button calls me a modal.js where I have the following code:

<script>
    //Confirm Advanced Usage
    $("#del").click(function(){
    bootbox.confirm({
    size: "small",
        message:"Deseja mesmo deletar este Registro?",
        buttons:{
            confirm:{
            label:'Sim, desejo!',
            className:'btn-success'
            },
            cancel:{
                    label:"Não desejo!",
                    className:'btn-danger'
                }
        },
        callback:function(result){
             console.log(response);
            }
    })
});

</script>

The above script uses confirm of bootbox.js

My question is how to make this button perform the delete function of

class Conexao(){

    function Conexao(){}

    function Inserir(){}

    function Update(){}

    function Select(){}

    /*executar está função abaixo*/

    function Deletar(){}

}

I can not get the function right inside the class.
