Hi Cholet,   
Thanks for using Syncfusion products.   
You can set the input value to the autocomplete dataSource by converting the string data to the JSON object. Refer to the following code example:  
public JsonResult text(string data) 
            var userData = new UserData() { text = data }; 
            UserData[] arr = new UserData[] { userData }; 
            string json_data = JsonConvert.SerializeObject(arr); 
            return Json(json_data, JsonRequestBehavior.AllowGet); 
We have added the input value to the autocomplete dataSource by using the button click event.   
Refer to the following code example:   
function onclick() { 
        var data = $("#input").val(); 
            url: "/Home/text", 
            data: { data: data }, 
            type: 'POST', 
            dataType: "json", 
            success: function (result) { 
                var data1 = JSON.parse(result); 
                var obj = $('#selectcar').data("ejAutocomplete"); 
                obj.option("dataSource", obj.model.dataSource); 
                obj.option("fields", { text: "text" }); 
Refer to the following sample:

Thanks, but in your example, I must to click on a button to see the autocomplete.
It's not possible automatically ?
