When generating the action link on the server you could put some special placeholder for the UserID route value:

@Ajax.ActionLink(
    "Edit", 
    "EditUser", 
    "User",    
    new { 
        UserID = "__userid__" 
    },
    new AjaxOptions {
        OnSuccess = "ShowEditUserForm",
        UpdateTargetId = "EditUserDetails",
        InsertionMode = InsertionMode.Replace,
        HttpMethod = "Get"
    }, 
    new { 
        @class = "button", 
        id = "EditUserButton" 
    }
) 

and then when you assign a value to the hidden field in javascript you could update the action link href as well:

$('#EditUserButton').attr('href', function() {
    return this.href.replace('__userid__', $('#NewUserID').val());
});
