How to run my class object with ajax jquery in PHP

Question

I am developing a theme and currently working on import data process. Radium one click import working really fine for my but I want to add some minor change. I have two demos for my client, family law and personal law. I want to give her a choice so that she can install which one she wants in single install. Currently me demo was installed with button click, I just disabled that functionality by jquery e.perventDefault() function to check which button is clicked so that I can set my demo files accordingly. Its working good and I am able to send my file names properly through ajax $_POST and getting those values in my PHP file.

The real issue is that it never imports my data any more. It sets my file names but does not start my import process. How can I start my import process again ? Here is my code.

$('.import-process .import-start').click(function(e){
        e.preventDefault();
        alert('family-law');
        $.ajax ({
            type: "POST",
            url:"path to my file",
            data: "family=family",
            success: function(data) {
                console.log("message sent!");
                alert(data);
            }
        });
    });

With this data I am just getting my file names and nothing else at all. Now kindly let me know how can I start my import process either in PHP file or in js file I am totally no where by now. Thanks Here is full code:
