why my js is not triggering when page refreshed or page loads for first time ? Edited

[aravinthelangovan]

My code is,

<script>

AJS.toInit(function () {  

var new_type = AJS.$("h1").text();
if (new_type == "Create Issue"){
AJS.$('.aui-header .aui-button.aui-button-primary.aui-style').hide(); //for disabling the create button for the particular page
}

});

</script>

The above mentioned code works fine in the snippets and any other action performed after page loads. But, in my scenario I want to hide the create button whenever page gets loaded or refreshed... I don't know where I'm mistaken and I'm also used JIRA.bind(JIRA.Events.NEW_CONTENT_ADDED, function (e, context) { 

});

this also not worked....
