Numbering of equation is reset after a page break block

I number equations using \label command.
After a page break block (not \pagebreak command of Latex) the numbering of equations is reset.
Suppose at the end of page 1 the last number of the equation is 8, then the first numbered equation on page 2 is numbered 1 not 9.
If I get rid of the page break block, there is no problem in numbering. The number increases as usual as in Latex file.
How can I avoid this number-reset problem.
The Custom MathJax Config I use is as follows.
——————————————

MathJax = {
  tex: {
    inlineMath: [['$','$'],['\\(','\\)']], 
    processEscapes: true,
    tags:"ams"
  },
  options: {
    ignoreHtmlClass: 'tex2jax_ignore|editor-rich-text'
  }
};
