jQuery Grid Plugin - jqGrid

My Problem is one i start application and click on jqgrid add button then it pick add property. After that if i click on edit but then it also pick the add button property.

Again if i start application again and this time if i chose edit button(Suppose i already have data in grid without hitting add button) this time edit form populate with edit property. Now click on add button now it pick edit form property. I could not understand what's going on.

 

thanks in advance.

 

jQuery.extend(jQuery.jgrid.edit, {
ajaxEditOptions: { contentType: "application/json" },
recreateForm: true,
jqModal:false,
reloadAfterSubmit:true,
closeOnEscape:true,
closeAfterEdit:true,
closeAfterAdd:true,
afterSubmit: function(response){
var success = false;
if(response.responseText == "added"){
// alert("Data added successfully");
$('#edit').trigger('click');
}
if(response.responseText == "edited"){
// alert("Data edited successfully");
$('#edit').trigger('click');
}
if(response.responseText == "wrongApp"){
alert("Wrong app");
}
return[true,"success",null];
},

top: 100,

height: 600,
width: 500,
closeAfterSubmit:true,

// mtype: 'POST',
serializeEditData: function (postData) {
if (postData.name == undefined) { postData.name = null; }

//alert(JSON.stringify(postData));
var elemId;
$('[name=chkboxId]:checked').each(function() {
elemId = $(this).val();
});
var postDatas=JSON.stringify(postData);

postDatas = postDatas.substring(0, postDatas.length -1);

var elemIdJson = ","elem":"";
var elemIdJson = elemIdJson+elemId;
var elemIdJson = elemIdJson+""}";
var postDatas=postDatas.concat(elemIdJson);

return postDatas;

}

});
