And an important problem is how can I naming them. please help me

Answer 1

We can do naming and reading fields that create dynamically these is your answer:

<div>
     <input type="radio" id="radio_1" name="radio1" value="1" /> 1<br />
</div>

and in Js:

for(i=2;i<=8;i++){
    $("div")
        .append($("#radio_1")
        .clone().attr({"id":"radio_"+i,"value":i}))
        .append(" "+i+"<br />");
}
$(":radio").click(function() {
    var radioID = $(this).attr("id");
    alert("by selector (:radio): " + radioID);
});

$("input[name=radio1]").click(function() {
    var radioID2 = $(this).attr("id");
    alert("by groupname: " + radioID2);
});

you and commentators can see it in jsfeedle
