[AJAX] Почему при вводе в input идет редирект на страницу с результатом?

$(document).ready(function(){
	$('#search_str').on('change input',function(e){
		console.log(e)
		e.preventDefault();
		var url = LANG_URL
			if($(this).val().length > 0){
				$.ajax({
				url: "/ajax/live-search/" + $(this).val() ,
				type: 'GET',
				dataType:'json',
				contentType: 'application/json; charset=utf-8',
				data:{},
				success: function(data) {
					$('.search-similar').html(' ')
					var location = $('#search_str').attr('data')
					var search_val = $('#search_str').val()
					var search_result
					if((data.text && data.text.length > 0) && (data.category && data.category.length > 0)){
						$('.search-similar').show()
						for( var i = 0; i < data.text.length; i++) {
							if(location){
								$('.search-similar').append("<li class='search-similar-item'><a class='search-similar-item-link' href='" + url + "list/q-" + data.text[i] + "/location'><span class='search-similar-item-value'>" + search_val + "</span><span class='search-similar-item-text'>" + data.text[i] + "</span></a></li>");

								search_result = data.text[i]
							}

						}
					} else {
