Try this, add your code on the start_count... then make sure to add a boolean to run your code only once.

$(function() {
    var oTop = $('#counter').offset().top - window.innerHeight;
    $(window).scroll(function(){

        var pTop = $('body').scrollTop();
        console.log( pTop + ' - ' + oTop );   //just for your debugging
        if( pTop > oTop ){
            start_count();
        }
    });
});

function start_count(){
    alert('start_count');
    //Add your code here
}
