[4.6 GUI] Selectable list of object for things like inventory, etc.

I feel like I'm getting nowhere with it. I'm trying to make a widget for inventory/whatever items. Each item can be selected with mouse by clicking it. The only problem? It get unselected right when player clicks something different.

Because of it I've decided to reselect it once it gets deselected. But it doesn't work, I send message, not via SendMessage, obviously, to parent to decide which child object should be reselected. At first I've thought the code actually doesn't execute, but it does. It simply doesn't highlight it back.

Here's the code:

     public void ensureSelection() {
         //this function will crawl through the child widgets and reselect one with proper ID. Might be laggy
         //for categories with large amount of objects, however we'll worry about that if it start to give
         //issues.
         GameObject child;
         
         for (int i=0;i<this.transform.childCount;i++) {
             child = this.transform.GetChild(i).gameObject;
             ObjectSelectionWidgetMeta oswm = child.GetComponent<ObjectSelectionWidgetMeta>();
             if (oswm!=null) { 
                 if (oswm.ID==LevEditGlobals.currentObject){ //woohoo, found widget with our ID!
                     Selectable sel = child.GetComponent<Selectable>();
                     if (sel!=null){
                         sel.Select();
                         Debug.Log("Selected!");
                     } //selecting it.
                     break;    //we've found it so we can break out of for early, no real need to loop thru rest
                             //of children now we found proper one.
                 }
             }
         }
     
     }

And before anyone asks, yes I've thought about using Toggles with togglegroups, but they require graphic for "toggled" thing. I need color tint.
