jQuery: building a form dynamically from an array with a for loop

Question

I have a jQuery function that receives id of div element and json array

function FormBuilder(selector,myList){
    for (var i = 0 ; i < myList.length ; i++) {
        var rowHash = myList[i];
        if(rowHash['id'] > 0 ){
            $(selector).append('<form id="DialerInfo">');
            for (var key in rowHash) {
                $(selector).append(key +': <input type="text" name="' + key + '" value="' + rowHash[key] + '"><br/>');
            }
            $(selector).append('</form>');
        }
    }
}

And I expected this to build a proper form, i.e. all inputs should be between <form> and </form> tags. But I'm receiving something completely different:
First goes
<form id="DialerInfo"></form> then below all input fields. Why are they outside the form tags? does jQuery close all tags automatically? how to prevent this behavior then?

DOM creation using jQuery doesn't work like string concatenation

You can create a form and append all the elements to it

function FormBuilder(selector, myList) {
  var $form = $('<form id="DialerInfo"></form>').appendTo(selector);
  for (var i = 0; i < myList.length; i++) {
    var rowHash = myList[i];
    if (rowHash['id'] > 0) {
      for (var key in rowHash) {
        $form.append(key + ': <input type="text" name="' + key + '" value="' + rowHash[key] + '"><br/>');
      }
    }
  }
}

//use

$.each(arrayorJSON,function(KEY,VALUE){
    //YOUR CODE HERE
})

//it is a jquery looper which accepts both array and json values and compatible with all browsers instead of for loop
