dwr返回函数不执行，怎么解决
用dwr执行插入，返回函数不执行。点击会执行了插入，就是不调用返回函数，代码如下

function insertWorkPlan(obj){

		    if(button_onsubmit()){

		    	var trobj=j$(obj).parent().parent();

		    	var programName=j$(trobj).find("select[name=programName]").val();

		    	var workTime=j$(trobj).find(":input[name=workTime]").val();

		    	var workBreak=j$(trobj).find(":input[name=workBreak]").val();

		    	var workDiscretion=j$(trobj).find(":input[name=workDiscretion]").val();

		    	var finishDate=j$(trobj).find(":input[name=finishDate]").val();

		    	var finishStatue=j$(trobj).find("select[name=finishStatue]").val();

		    	var headPepole=j$(trobj).find(":input[name=headPepole]").val();

		    	var remark=j$(trobj).find(":input[name=remark]").val();

		    	var coordinationObject=j$(trobj).find(":input[name=coordinationObject]").val();

		    	var superviseTime=j$(trobj).find(":input[name=superviseTime]").val();

		    	var taskType=j$(trobj).find("select[name=taskType]").val();

		    	var myworkplan =programName+","+workTime+","+workBreak+","+workDiscretion+","+finishDate+","

		    		+finishStatue+","+headPepole+","+remark+","+coordinationObject+","+superviseTime+","+taskType;

		    	//DWREngine.setAsync(false);  

		    	WorkPlanProxy.insertWorkPlan(myworkplan,function(data){workBack(data,obj,myworkplan);});

		    	//DWREngine.setAsync(true);  

		    }

		  }

		  function workBack(data,obj,myworkplan){

			  alert(data+"===");

			  var trobj=j$(obj).parent().parent();

			  var datas=myworkplan.spilt(",");

			  j$(trobj).empty();

			  j$(trobj).html(

			    '<td>'+datas[0]+'</td><td>'+datas[1]+'</td><td>'+datas[2]+'</td><td>'+

			    datas[3]+'</td><td>'+datas[4]+'</td><td>'+datas[5]+'</td><td>'+datas[6]+'</td>'+

		        '<td>'+datas[7]+'</td><td>'+datas[8]+'</td><td>'+datas[9]+'</td><td>'+datas[10]+'</td>'+

		        '<td>'+ '<a href="#" onclick="updateWorkPlan(this)">修改</a>&nbsp;&nbsp;<a href="#" onclick="deleteWorkPlan(this)">删除</a>'+

		        '</td>'

			  );

		  }

求高手解决，谢谢。
------解决方案--------------------
把这个function insertWorkPlan(obj)函数名改下  别和WorkPlanProxy.insertWorkPlan 一样！试下。。。。

------解决方案--------------------
1.先在dwr测试界面测试方法能否成功执行
2.如果可以执行，<convert converter="bean" > json自动转换成bean的 配置删除 ，再在dwr测试页面里<
