There are couple of ways to call it
1. using scriptManager
2. using Page.RegisterStartupScript method (without scriptManager)
withscript manager
ScriptManager.RegisterStartupScript(this, this.GetType(), "methodName","methodName('" + Name + "','Keyword',+'Region');", true);
without script manager
Page.RegisterStartupScript("methodName", "methodName('" + Name + "','Keyword',+'Region');");
Static JavaScript files do not get fed through ASP.NET normally, I think you need to make the function on page and then call it from code behind
