addEventListener multiple times in a click event

I have a problem trying to catch a event in a javascript file. I need to handle some buttons when these are clicked. They have differente behaviour, for example, some add some elements, other can multiple add elements, or delete them.

I have 4 buttons in a panel (search, add, add+ and delete). To be precise, I'll explain the problem with the search button.

I have a function "search" that takes the button from de document, and link to a eventListener

btn_search = document.getElementById('searchBtn');
btn_search.addEventListener("click", search);

Then, after click over btn_search, a modal display with some inputs and a submit button. When I click over the button, the modal closes with the data that I need. In this situation the system works well, but when I want to operate with another functions (add, delete, or the same search), this last tasks execute but all the other previous operations executes too. It's as if repeat all the secuence together when a new operation it's coming.

This is the code that I use for search, its similar in the other operations

function search(event) {
event.stopPropagation();
buildModal(1);
$('#modal_gid').modal('show');

btn_modal_footer.addEventListener("click", search_elems); //button to attach function to "search button" in button

function search_elems(event) {
    event.preventDefault();
    let code = input_code.value;
    if (code != null && code != "")
        $.ajax({ 
            url: base_url.value + 'index.php/ajax_get_elems',
            method: 'post',
            dataType: "json",
            data: { "code": code },
            success: function (response) {
                success functions
            }
        });
    else
        handler_errores_code(2)
}

I tried with removeEventListener but not work. With a counter or flag variables too.

Thanks!

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
