Regex not working in getting the exact word count

Below is my code where on running the application the user can first a template and on clicking that template we can see ck editor along with a drop down beside to ckeditor where user can see multiple items on choosing a particular item in drop down the corresponding text in the ckeditor gets changed when user gives nothing in the editor and click on complete button i should get the word count as zero and when user gives any words in the editor i need to get that word count suppose if i give abcd i need to get the count as 4 and if i don't give anything i need to get count as zero but with the current code i am get word count as -2 for first drop down,0 for second drop down,-3 for third drop down and 4 for third drop down when there is no text in the editor i need to get zero but i am getting these as word counts
