CSR custom colum not available in CurrentItem

Question

I created a new sharepoint content type with created custom columns, then created a new task list. I made my content type as default. If I try to get the value of my created columns (text) I get an undefined (of course I use the internal name of the column).

Do I get only the value of default sharepoint columns? Or am I missing something?

(function (){
    //init
    var inCtx = {};
    var mfield = {};
    inCtx.Templates = {};

    inCtx.Templates.Item = ItemOverride;

    inCtx.Templates.Header = "<div>";
    inCtx.Templates.Footer = "</div>";

    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(inCtx);

    function ItemOverride(itemCtx){
        var result = "";
        result += "<h4>";
        result += itemCtx.CurrentItem.Title + " ";
        result += itemCtx.CurrentItem["MYCOLUMN"];
        result += "</h4>";

        return result;
    }

})();

I added console.log(itemCtx.CurrentItem) to my function:

Fixed it!

I had to click Edit Page -> Edit Webpart. There I changed the view from "< Current View >" explicit to the View - even if it was the same.

Now I can get my stuff done, thx @all!
