Replace JQuery code

Hi,

Currently we are using JQuery code for autocomplete. Which send an Ajax call to my action which create json object in result.
For eg. I am sending partial name, and in json object I am getting json object with all names containing partial name. On success I am populating the text box with dropdown options.

For above scenario I wish to use DHTMLX. Kindly guide, as I am not aware how do I proceed - with dhtmlxajax or enableFilterMode of dhtmlxcombo.

I tried using the below code:
var ub = new dhtmlXCombo(“issuer”, “”, 200);
var issuerName = document.getElementByID(“issuer”);
ub.enableFilteringMode(true,“IssuerListAjax.do?issuer=issuerName”,true,true);

… after this how do I capture the json result send by Action?
