BUTTON - CANNOT READ PROPERTY 'APPLY' OF UNDEFINED

Hi guys,

I'm trying to add another button to Social Feed messages.

I extended SocialFeed and modified the ESNFeedConfig like this:

 addResolveButtonConfig: function(){ 
                //return if config was modified 
                if(ESNFeedConfig.IsModified){
                    return;
                }
                //get initial config of post
                 var postConfig = ESNFeedConfig.postConfig; 
                 //get the location where need to add the button
                 var actionsConfig = postConfig.items[0].items[4].items[1].items; 
                 //create config for new button
 
				var resolveButtonConfig = {
					className: "Terrasoft.Button",
					style: Terrasoft.controls.ButtonEnums.style.GREEN,
					click: {bindTo: "onResolvedOnlyClick"},
					caption: "Resolve",
					visible:true,
					classes: {
						imageClass: ["actionsButtonImage"],
						textClass: ["actionsButtonText"], 
						wrapperClass: ["actionsButtonWrap", "actionsColor", "likeButtonImageConfig"]
					},
					markerValue: "Resolve"
				};
                 //add button to the array
                 actionsConfig.splice(6, 0, resolveButtonConfig); 
                // change the config
 
                 ESNFeedConfig.postConfig.items[0].items[4].items[1].items = actionsConfig; 
                 ESNFeedConfig.IsModified = true;
                },

Added the button perfectly where I need it but clicking on it is showing the following error in the console:

polyfills-es5.js:1 Uncaught TypeError: Cannot read properties of undefined (reading 'apply')
    at i.callModelMethod (all-combined.js:41:208448)

    at HTMLSpanElement.k (all-combined.js:6:108390)
    at t.value (polyfills-es5.js:1:22418)

I defined the click method in the same place where created the configuration. What I'm missing? 

Similar to this post: https://community.terrasoft.ua/questions/button-cannot-read-property-ap…

In the last message that post suggest something about adding the click method in the ViewModel, but not sure what that means.

Any help would be really appreciated!

Thanks!
