My scripts are not working properly

So my scripts come in three parts 1st part is Keybind 2nd part is KeyController and finally the 3rd part is function i want done if key is pressed. But issue is KeyController isnt pulling Keybind scripts unless object in the inspector is selected during play mode. If i pause it then select Object that has scripts on it after i resume it magically works. Its important to note if Main Object that has codes is selected then scene is played it still has these errors

Errors
