Jquery JQGrid不支持基于多个筛选条件的自动完成

我有一个JQGrid，有多个标题和两列，并启用了自动完成功能。 当我转到JQGrid Filter并选择一个要在启用Autocomplete的情况下过滤的列时，它工作得很好，Autocomplete函数按预期调用。但是，当我为同样包含自动完成功能的筛选结果添加第二列时，自动完成功能对于新筛选器不起作用，并且它还禁用了前一个筛选器上的自动完成功能

自动完成的代码如下所示：

Common.setAutoComplete = function (id, url, select, change, extraParams)
    {
      id.autocomplete(
      {
        source: function (request, response)
        {
            alert("start of autocomplete");
            $.ajax(
            {
                url: url,
                data: { query: request.term, extraParameters: extraParams },
                dataType: 'json',
                type: 'POST',
                success: function (data)
                {
                    if (data)
                        response(data);
                }
            });
        },
        delay: 10,
        minChars: 1,
        matchSubset: 1,
        matchContains: 1,
        cacheLength: 400,
        select: select,
        change: change,
        autoFill: true
    });
    };

JQGrid的输出如下所示：

var invalidRows = [];
var allRowsValid = true;
var validRows = [];
var IssuerListTablerowId;
var IssuerListTablehasDefaultFilter = true;

var currentTableId = 'IssuerListTable';
     $(document).ready(function(){
