Text Input for Positive Integers Only

I'm trying to make a number input that is for only positive numbers. I have the following html:

As you can see, I've implemented ng-pattern and min value but neither one works. In the controller:

quantity: number=1;

i=1;

plus(){

this.i++;

this.quantity=this.i;

}

When I add the following to the controller, I get the error " Property 'match' does not exist on type 'number'"

this.quantity.match(/^(0|\+?[1-9]\d*)$/g);
