"ows_LinkTitle" returns "undefined" for a folder created using CSOM in SP2010 list

Question

I have created a folder in a SP2010 list using CSOM. When I try to fetch if the folder exists in list, it returns "Undefined" to the SPService that I run.

For all folders created using GUI the name of folder is returned. Also, I have tried setting up the value manually while creating the folder using this.oListItem["ows_Title"]="My Folder"; yet folder does not seem to get this property.

Code for folder creation-

clientContext = new SP.ClientContext.get_current();  
    oWebsite = clientContext.get_web();  
    oList = oWebsite.get_lists().getByTitle("List");  
    itemCreateInfo = new SP.ListItemCreationInformation();  
    itemCreateInfo.set_underlyingObjectType(SP.FileSystemObjectType.folder);  
    itemCreateInfo.set_leafName("My Folder");
    var name=itemCreateInfo.get_leafName();
    alert(name);
    this.oListItem = oList.addItem(itemCreateInfo);
    this.oListItem.update();
    clientContext.load(this.oListItem); 
    this.oListItem["ows_LinkTitle"]="My Folder";
    this.oListItem["ows_Title"]="My Folder";
    alert(this.oListItem["ows_LinkTitle"]);
    alert(this.oListItem["ows_Title"]);
    this.oListItem.update();
    clientContext.load(this.oListItem);  
    clientContext.executeQueryAsync(  
        Function.createDelegate(this, successHandler),  
        Function.createDelegate(this, errorHandler) 
     );  
     function successHandler() {  
        alert("Folder Created"); 
    }  

    function errorHandler() {  
        alert("Folder Creation Errored"); 
    }

Try below code

clientContext = new SP.ClientContext.get_current();  
oWebsite = clientContext.get_web();  
oList = oWebsite.get_lists().getByTitle("List");  
itemCreateInfo = new SP.ListItemCreationInformation();  
itemCreateInfo.set_underlyingObjectType(SP.FileSystemObjectType.folder);  
itemCreateInfo.set_leafName("My Folder");
this.oListItem = oList.addItem(itemCreateInfo);
this.oListItem["Title"]="My Folder";
this.oListItem.update(); 
clientContext.load(this.oListItem);
clientContext.executeQueryAsync(  
    Function.createDelegate(this, successHandler),  
    Function.createDelegate(this, errorHandler) 
 );  
 function successHandler() {  
    alert("Folder Created"); 
}  

function errorHandler() {  
    alert("Folder Creation Errored"); 
}
