Why route() function does now works using laravel?

In my laravel package the route does not working it is showing following incorrect route in debugger

Request URL: http://localhost:8000/%7B%7B%20route('contact')%20%7D%7D

However my route is as following

Route::group(['namespace' => 'ayazdev\Contact\Http\Controllers'], function(){
    Route::get('contact', 'ContactController@index')->name('contact');
    Route::post('contact', 'ContactController@send')->name('sendForm');
});

And following is where I am calling the route

$(function(){
    $("#contact-form").submit(function(e) {
        var form = $(this);
        $.ajax({
               type: "POST",
               url: "",
               data: form.serialize(), 
               success: function(data)
               {
                   alert(data); 
               }
             });
        e.preventDefault(); 
    });
});

if above detail does not enough to understand then you can kindly check it on github.

Can someone kindly guide me why it is now working, I will appreciate. Thanks
