res.render with href but not with jquery http get

I am new to Node.JS and writing a program on expressjs. I have an app.js node program with following route

app.get('/registration2',function(req,res) {
    console.log("app.js");
    res.render('registration2');
});

This works fine when I use it from menu using

<li><a href="/registration2">Become Member</a></li>

but when I call similar using jqury it doesnt render page registration.

app.get('/pr1/:price?',function(req,res) {
    var  price = req.params.price;
    console.log(price);
    res.render('registration2');
});

I used console.log(price) just to check whether it is capturing varible price correctly and i found that console.log does show correct result my jquery is as follow

<script>
$(document).ready(function(){
    $("#btn1").click(function(){
        $.get("/pr1/499");
        alert("OK");
    });
});
</script>
