How do I call a jQuery function from Default.aspx.cs

var Progress = "20";
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "scr", "setProgress(" + Progress + ");", true); 

JavaScript runtime error: 'setProgress' is undefined

                $(".progressbar").width(progressBarWidth).html(progress + "% ");
