Post title is being displayed instead of Page title

I’ve created a simple function to display the page title. I’ve had to use some conditionals to try and change the title on the blog to use wp_title(); because get_the_title ends up displaying a post title instead of the page title. I’ve used this code but it doesn’t seem to work, I’m still getting a post title.

function ls_page_title() {

		$checkbox = get_post_meta( get_the_id(), 'ls_disable_page_title', true);
		// $pageTitle = get_post_meta( get_the_id(), 'ls_page_title', true) ? get_post_meta( get_the_id(), 'ls_page_title', true) : get_the_title();

		if ( is_page( get_option('page_for_posts') ) ) {
			$pageTitle = wp_title('', false);
		}
		else {
			$pageTitle = get_post_meta( get_the_id(), 'ls_page_title', true) ? get_post_meta( get_the_id(), 'ls_page_title', true) : get_the_title();
		}

		if ( $checkbox !== '1' ) {
			echo '<h1 class="page-title">' . $pageTitle . '</h1>';
		}

	}
