If you want the dialog to stay open, add a return false to the callback, ergo:

$('#delete_btn').click(function(event) {
    event.preventDefault();

    bootbox.prompt("Are you sure you want to done the record?<br/>Write 'done' below to confirm!", function(result) {
        if(result !== null){
            result = result.toLowerCase();

            if(result === 'done') {
                /* submit your form */
            } else {
                alert('please enter something in textbox');

                return false;
            }
        }
    });
});

You could also always return false, and then manually close the prompt only in the successful state:

$('#delete_btn').click(function(event) {
    event.preventDefault();

    bootbox.prompt("Are you sure you want to done the record?<br/>Write 'done' below to confirm!", function(result) {
        if(result !== null){
            result = result.toLowerCase();

            if(result === 'done') {
                /* submit your form, then... */
                bootbox.hideAll();

                // or $('.bootbox').modal('hide');
            } else {
                alert('please enter something in textbox');
            }
        } else {
            bootbox.hideAll();
        }
    });


    return false;
});
