debugging ten thousand lines of code around a week found out happening due to ngDoCheck

- I am trying to increase the count of the operations performed **animalEvolution File** - I am able to increase the value in this method animalActionsRecordedTimely but after I pass into this method ngDoCheck I dont see increase in value. - so I added ngDoCheck in my file animalEvolution itself but still its taking to animalBreath file ngDoCheck - I tested by keeping debugger after I did stepover for this line **[login to view URL]([login to view URL](true,[], sourceData));** and saw it in the console using this line [login to view URL] I saw the value changed to 1. - but after it reaches ngDoCheck and there in the console if I see the value the value got changed to 0 for this line [login to view URL] **animalBreath File** - same functionality they use it another file but there the value is increasing in both the methods animalsSwimmingAllRecordedNight and ngDoCheck - value got increased due to this statement **[login to view URL] = this.animalsAliveIncrement+1;** and [login to view URL]([login to view URL](true,[], sourceData)); - Each file is 10,000 lines of code, so I posting each file in separate gist. - When I was debugging I came to see three different ngfactory files not sure why its happening and a VM file too - can you tell me how to fix it **animalEvolution File** [login to view URL] **animalBreath File** [login to view URL] animalActionsRecordedTimely(textName: any) { if ([login to view URL]) { [login to view URL] = [login to view URL][[login to view URL]].eventName; [login to view URL][[login to view URL]].eventName = textName; if([login to view URL]>0){ this.animalsDeathDecrement=0; [login to view URL] = true; [login to view URL]([login to view URL]); } //let sourceData = {"animalsTalking":[login to view URL],"destinationEvent":[login to view URL],"occurence":[login to view URL],"action":[login to view URL]}; let sourceData = {"animalsTalking":textName}; [login to view URL] = this.animalsAliveIncrement+1; //[login to view URL]([login to view URL]); //[login to view URL]([login to view URL]); [login to view URL](textName); [login to view URL](textName); [login to view URL]([login to view URL](true,[], sourceData)); return; } if (textName == undefined || textName=='') { $("#AnimalsTeethNameError").addClass('mandatoryField'); $('#txtArea').attr("title","Event description can not be empty."); $('#AnimalsTeethNameTxt').addClass('actionanimalsJeansd'); } else { [login to view URL](); [login to view URL](); } [login to view URL]({ "name": textName, "aptDate": [login to view URL]}); [login to view URL](); [login to view URL](); } undo(){
