Unable to select a result from the select2 search results

I am using the select2 for on of my search boxes. I'm getting the results from my URL but I'm not able to select an option from it. I want to use the 'product.productName' as the text to be shown after selection. Is there anything that I have missed out or any mistake that I have made. I have included select2.css and select2.min.js,jquery.js

  function dataFormatResult(product) {
        var markup = "<table class='product-result'><tr>";

        markup += "<td class='product-info'><div class='product-title'>" +     product.productName + "</div>";
        if (product.manufacturer !== undefined) {
            markup += "<div class='product-synopsis'>" + product.manufacturer + "</div>";
        }
        else if (product.productOptions !== undefined) {
            markup += "<div class='product-synopsis'>" + product.productOptions + "</div>";
        }
        markup += "</td></tr></table>";
        return markup;
    }

    function dataFormatSelection(product) {
        return product.productName;
    }
    $(document).ready(function() {
        $("#e7").select2({
            placeholder: "Search for a product",
            minimumInputLength: 2,
            ajax: {
                url: myURL,
                dataType: 'json',
                data: function(term,page) {
                    return {
                        productname: term 
                    };
                },
                results: function(data,page) { 

                    return {results: data.result_object};
                }
            },
            formatResult: dataFormatResult, 
            formatSelection: dataFormatSelection, 
            dropdownCssClass: "bigdrop", 
            escapeMarkup: function(m) {
                return m;
            } 
        });
    });

This is my resut_object

"result_object":[{"productName":"samsung galaxy s3","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Silver;32GB"},{"productName":"samsung salaxy s3","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Graphite;32GB"},{"productName":"samsung galaxy s3","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Silver;16GB"}]

Since I was using AJAX, what worked for me was returning something as the ID on processResults:

$(field).select2({
   ajax: {
        // [..] ajax params here
        processResults: function(data) {
            return {
                results: $.map(data, function(item) {
                    return {
                        // proccessResults NEEDS the attribute id here
                        id: item.code,
                        // [...] other attributes here
                        foo: item.bar,
                    }
                })
            }
        },
    },
});

You are missing id attribute for result data. if it has not, it makes option "unselectable".

Example:

            $('#e7').select2({
                    id: function(e) { return e.productName; },
            });

The id param can be a string related to the object property name, and must be in the root of the object. Text inside data object.

var fruits = [{code: 222, fruit: 'grape', color:'purple', price: 2.2},
  {code: 234,fruit: 'banana', color:'yellow', price: 1.9} ];

$(yourfield).select2(
 {
   id: 'code',
   data: { results: fruits, text: 'fruit' }
 }
);

I have faced the same issue,other solution for this issue is:-

In your response object(In above response Product details object) must have an "id" as key and value for that.

Example:- Your above given response object must be like this

{"id":"1","productName":"samsung galaxy s3","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Silver;32GB"}

SO you don't need this id: function(object){return object.key;}
